Flexible Drainage Couplings

Flexible drainage couplings serve as important components within drainage systems. They offer easy connections between pipes of varying materials, sizes, and shapes.

Made from EPDM rubber, our flexible drainage pipe couplings offer a versatile and reliable solution for coupling drainage, sewerage, and plumbing installations, without the need of time-consuming fabrications or costly material-specific branded couplings. Engineered to the highest industry standards including BS EN 16397, BS EN 681-1, ETA-09/0248, and WIS 4-41-01, these flexible pipe couplings are at the forefront of quality and durability.

Our couplings can easily accommodate minor pipe misalignments and movements, ensuring a watertight seal that prevents leaks and blockages throughout the critical drainage infrastructure.

Features & Benefits of Flexi Couplings

Our flexible drainage couplings are manufactured with advanced features:

Fitted Rubber Profile: The couplings' specially designed rubber profile ensures the clamps remain tightly in place during transportation and installation, minimising the risk of leaks or failures.
Reliable Sealing: The internal sealing features of our couplings create a tight and secure pipe connection, effectively preventing any water or wastewater leakage.
Versatile Compatibility: The EPDM sealing material allows our flexible couplings to provide a reliable seal even when connecting to rough surface pipes, such as those made from concrete.
Stainless Steel Bands: By using stainless steel fastening components instead of spot welding on the couplings, we've eliminated the negative impacts and potential points of failure associated with welded connections.
Engineered to Standards: Manufactured to the requirements of BS EN 16397, our flexible drainage couplings meet the highest industry quality and safety standards.

Flexi Drainage Couplings - Straight

Our straight flexible pipe couplings are the ideal solution for underground drainage systems where the additional reinforcement provided by a shear band is not required. Designed to provide a secure, watertight connection, these flexi couplings are perfectly suited for use in situations where the pipes are not subject to significant earth loads or shear forces.

Our standard straight flexible pipe couplings are available in 100mm, 150mm, 160mm and 180mm in diameter, and from 105mm to 200mm with metal wrapped body. This comprehensive selection ensures you can find the perfect fit for your specific drainage project, whether it involves connecting PVC pipes or interfacing with other common drainage materials like clay, salt glaze, supersleve, asbestos cement, or pitch fibre.

By eliminating the need for a shear band, our straight flexible couplings offer a streamlined and cost effective option for underground drainage installations. The flexible MDPE rubber construction allows the couplings to easily accommodate minor pipe misalignments, while still creating a durable, long-lasting seal that prevents leaks and maintains the integrity of the overall drainage system.

Flexi Drainage Couplings - Stepped

Flexible drainage adaptors are the essential solution for connecting pipes of different sizes and materials. These versatile connectors also allow you to securely interface pipes with other critical drainage infrastructure, such as manholes, inspection chambers, and septic tanks.

At the core of our flexible adaptors are two robust clamping bands positioned at either end. These bands create a tight, secure seal by clamping the moulded sleeves firmly onto the connected pipes. This innovative design ensures a watertight, durable join, even when transitioning between pipes of vastly different compositions, from traditional clay to contemporary PVC.

We offer a comprehensive range of flexi adaptors capable of bridging a wide variety of pipe size combinations. Whether you require a coupling to connect a 100mm pipe to a 150mm pipe, or need to interface a 160mm drainage line with a manhole, our adaptors provide a reliable solution.

By simplifying the process of joining dissimilar pipes and integrating drainage system components, our flexible adaptors play a crucial role in the successful installation and long-term performance of modern plumbing and wastewater management networks.

Flexi Plumbing Couplings

In addition to our range of flexible drainage couplings, we also offer a selection of both straight and adaptor plumbing couplings designed for smaller diameter, low-pressure applications. These versatile plumbing couplings make them an ideal solution for emergency repair situations, as they can be quickly and easily installed without the need for any specialised tools.

Similar to our regular drainage adaptor couplings, the plumbing adaptor variants allow you to seamlessly join two pipes of different diameters. This compatibility, combined with their flexible design, makes them a valuable asset when working with our extensive Solvent Weld, Pushfit, and Multifit Waste Systems.

*Delivery to non-Industrial Scotland, Northern Ireland, and CH, LL, and CA postcodes can sometimes take slightly longer, although this is dependent upon the exact location.

If we are unable to deliver your order within the above timeframe for any reason, we will contact you to arrange an alternative delivery day. We use overnight carriers, so we are unable to arrange or confirm an exact time of delivery.

Some special or non-stocked items on our website have extended lead-times, which are displayed on the product pages in question – see below for more details.

Whilst every reasonable effort shall be made to keep to a delivery date, we cannot be held liable for any losses, costs, damages, or expenses arising directly or indirectly out of any failure to meet any estimated delivery date.

In the unlikely event of a late delivery, we will be unable to compensate you for any consequential loss, so please do not organise any plant or labour before you have received your materials.

DELIVERY CHARGES AND EXTENDED LEAD TIMES

Orders over £1,000 excluding VAT will be delivered free of charge. Orders under this amount will incur a charge of £15.00 + VAT. This applies to most stocked items and some items that are supplied directly from manufacturers. Orders of stocked items are generally delivered in 1-3 working days.

Some stocked items will incur a bulky or pallet charge due to their extreme weights or lengths:

Bulky items - £45.00 + VAT charge placed on orders that contain one or more bulky products. These items will be marked as bulky during the checkout process.
Palletised items - £60.00 + VAT charge placed on orders that contain one or more items that need to be sent and delivered via a pallet. These items will be marked as palletised during the checkout process.

A full list of stocked items can be found here.

Certain items, usually those sent direct from manufacturers, incur additional delivery charges and an extended lead time regardless of the order value, due to the restrictions placed upon us by our carrier and the extreme weights/lengths. These charges are applied instead of the standard £15.00 + VAT charge if the order is valued under £1,000 excluding VAT.

The following product ranges have extended lead times or incur additional delivery charges. Please click on each individual range for specific details.

SPLIT DELIVERIES

If you have ordered a mixture of goods that come both from us and direct from our manufacturing partners, you will be advised of this in your dispatch email. As the order is coming from two locations, you will receive two different deliveries. Delivery on direct items can have extended lead times and will need someone present to check and sign for the goods.

Occasionally, we don't have all items in stock at our main warehouse. If this is the case, we will endeavour to send the stock the same day from one of our other branches, in order to not delay delivery of the complete order. This may lead to a split delivery, dependant on the courier being used. We will contact you if there is going to be a delay due to this.

LABOUR AND MACHINERY

Please do not book machinery or labour until your goods have been received and checked over. Whilst every effort is made by our couriers to deliver your parcel within the stated timeframe, Drainage Sales cannot be held responsible for any additional costs incurred by delays outside of our control.

CHECKING AND SIGNING FOR ORDERS

SIGNED FOR POLICY – T&CS

All orders should be signed for. If you are unable to sign for your delivery, you can arrange with us for a neighbour to take delivery of your order. You can also advise us of a safe place where your order can be left, although we cannot take responsibility for any shortages or obvious damages.

Please ensure that you always check the number of packages that you are signing for. If there is an incorrect number of packages or any package appears damaged, you should note this on the signature panel and advise us so that we can rectify the issue as quickly as possible. Once goods have been signed for as being received ‘complete and in good condition’, any claims are not covered by the carrier’s insurance company.

Signing for goods as ‘unchecked’ makes any claims inadmissible, so please check the number of packages and look for any signs of any damage, noting any issues on the signature panel. Although the delivery drivers are busy, they are contractually obliged to wait whilst you check your delivery.

WHAT IF I CAN’T WAIT IN ALL DAY?

There is a ‘Notes’ section of the Basket review page where you can request for your goods to be left in a safe location – just tell us where to leave the order. Please not that we cannot take responsibility for any shortages or obvious damages if goods have not been signed for.

Please note that deliveries made by DHL (these are generally small orders with no pipe or bulky products) cannot be left in a safe location. You will be advised which carrier will be delivering your order by email at the point of dispatch.
