Flexseal are a Made in Yorkshire Silver Member
Flexseal design and manufacture the most comprehensive range of fully-approved low and non-pressure flexible couplings in the marketplace. Flexseal couplings are suitable for sewerage, drainage, plumbing and vent systems, and can be used with plastic, clay, concrete, cast iron and steel pipes.
Outstandingly high quality has been at the forefront of Flexseal’s success and all of our products are manufactured and tested to consistently meet UK and International approvals.
We provide excellent customer service - our external team frequently visit our stockists and our internal staff are always available to attend to any queries.
Flexseal couplings are manufactured for use when jointing pipes in sewerage, drainage and other non-pressure applications. They consist of an elastomeric sleeve with clamping bands. The clamp bands are manufactured from stainless steel.
EPDM has good or excellent resistance to oxidation, ozone, ultra-violet light and heat. This property makes the elastomer suitable for both underground and above ground applications
The product is manufactured for use in drains and sewers. Any substance not usually associated with this application could possibly be detrimental to the elastomer. In such cases, advice should be sought about the suitability of the elastomer to resist chemical attack. EPDM is not suitable for effluent contaminated by hydrocarbons. In these cases, Nitrile seals should be used.
Nitrile should be used when effluent is contaminated by hydrocarbons in below ground applications. In this environment Nitrile will provide a long service life. The nitrile compound used with Flexseal couplings is not suitable for use in pipelines carrying hydrocarbon liquids of high concentrations.
The performance of a Flexseal product is dependant upon maintaining contact pressure under the clamp band to ensure the seal remains tight. Our clamp bands can exert sufficient clamping pressure at the recommended tightening torque to ensure that there is adequate contact pressure even after 50 years of stress relaxation.
