Genuine Flexseal EPDM Plumbing Range Connectors from the Uniseal Shop - The price you see is the price you pay, no extra postage (that is included in the price). We operate as a UK business and happily export worldwide. We sell all sizes of the genuine Flexseal EPDM Plumbing Range on this eBay listing.  Check out our other eBay items HERE.

Beware of imitation, if it isn't a Flexseal it would be an inferior imitation. Our Flexseals come directly to us from the manufacturer in the UK, are guaranteed 100% genuine and we have a 30 day "No Quibble" return policy if unused.

If you would like to purchase Flexseals for delivery outside of the UK please contact me through eBay for the extra postage costs or find them directly on our website Since the weights of the parts vary it is impossible to determine the extra cost in every case and we are trying to keep your purchase cost down.

The Product - Flexseal - connect pipes to pipes using only one part and without using messy solvent glue.

Flexseal Plumbing products replace traditional plumbing hardware with an injection moulded EPDM unit and end clamps in Grade 1.4301 (304) stainless steel requiring no extra component parts. They were designed by Flexseal to solve many of the issues of pipe to pipe connections for low pressure connections.

The Flexseal EPDM Plumbing Range consists of EPDM straight connectors, EPDM rubber pipe Tees, EPDM rubber elbow connectors, EPDM rubber reducers and EPDM rubber end caps. Sometimes called rubber boots, an all encapsulating term for both EPDM and PVC varieties, the Flexseal product is at the top of retail offerings and is produced in the U.K. by Flexseal which is a subsidiary of Fernco.

The Flexseal developed EPDM coupling is the key to the liquid-tight seal. The flexible Flexseal EPDM unit with a higher coefficient of friction, higher elasticity and ridged internal connection face allows it to create a better liquid tight seal with a pipe than any other material such as cheaper flexible PVC which is widely used as a plumbing coupling. The ends are clamped with Grade1.4301 (304) stainless steel to provide a long lasting connection. The Flexseal EPDM coupling tightened to a low tightening torque of 6Nm provides a superior drip free connection and is less liable to slipping off from smooth pipes. This is important when the connecter is used internally or on the likes of hydroponic systems.

EPDM is a synthetic rubber made from ethylene and propylene and has excellent ozone and weather resistant properties.

Standard Flexseals are made to fit ABS, PVC, steel or any other pipes with an Outside Diameter from 24mm to 100mm.

The greatest assets to Flexseal products are that they have a quicker and easier installation process and can be removed and replaced at a later time. No more having to cut solvent welded fittings from pipes due to design changes or mistakes. Pipes and Flexseals can be removed and with care re-used time and again. Want to change the design of your system, simply release the stainless steel Unversal clip and remove the Flexseal. Flexseals are also ideal for a hydroponic system as they are re-usable. Although initially more expensive than solvent welded connections the first time that you have to replace solvent welded connectors and pipes will help you understand the benefits of Flexseal EPDM rubber boots.

Standard Pipe Sizes - Flexseals are designed for industrial processes and work flawlessly on any pipe including copper, gavanised steel, PVC and ABS pressure pipe which is generally thick walled. Other pipes come in different Outside Diameter (O.D.) sizes.

Service - We have an old fashioned view of service and have found that this has paid dividends for us as we grow our business, we are justifiably proud of our service record and our feedback reflects what our customers feel about us. Your feedback is important to both us at the Uniseal Shop and you the customer since excellent feedback allows us to maintain our Top Seller status, attracts a discount from eBay and enables us to keep our prices as low as is possible.

Delivery - We will get the Flexseal products to you as fast as we can. We ship every day to catch the last uplift from the local Royal Mail Post Office and items are normally all posted First Class. This often means that items are delivered the next day. Items over £20 are sent "Signed For". On many of our listings we do provide the "Next Day" delivery option which due to the variable size and weights of our packages cannot be accurately forecast before we send it. Our Next Day delivery charges covers most of our item weights, any residual in the actual postage cost will be refunded through your PayPal account. We are not in business to make profits from our customers postal charges and will keep those charges as low as possible! However if I were you I would not bother with next (working) day delivery, First Class is actually sometimes quicker particlarly at the end of the week.

Returns - We have an Absolute "No Quibble" 100% guarantee - If you find you no longer require your Flexseals for any reason within 30 days the Uniseal Shop will refund the full product cost as long as the Flexseal has not been used, or trial fitted etc. If the resealable bag has been opened or damaged this is not a problem. There is only a small charge to cover our initial Postage (not packing) costs and you will understand what this is when you post back to us.

How to return an item - Email the Uniseal Shop for a returns number, package your returning items up in the original packing and for most items you will need to send it/them back through a Post Office. The Uniseal Shop will refund your product costs through PayPal within one working day of receipt of the item.

Why do we provide this Returns service - EPDM Flexseals are a fantastic product that few people in the UK use due to the predominance of much less expensive but lower performing PVC connectors, we feel that we can be evangelical about the product. Put yourself at ease - trying the product from us will only cost you the postage! So even if you change your mind or find a better solution you can return your Flexseal items, we won't mind, at least you will have investigated the Flexseal EPDM Plumbing Range.
