About VIPSeal and VIP-Polymers
About VIPSeal starts with VIP-Polymers, a UK manufacturer with more than 100 years of experience in rubber sealing technology. The VIPSeal range includes flexible couplings, adaptor couplings and specialist pipe sealing products for drainage, repair and low or non-pressurised pipe applications.
Manufactured in the UK, VIPSeal products support contractors, merchants and installers who need reliable pipe connections across different materials, sizes and site conditions. Explore the page below to learn more about our manufacturing background, product standards, material options and wider VIPSeal product family.
VIP-Polymers manufactures over 3,000 products and has introduced many new proprietary products for pipeline applications, notably VIP-Weco, VIPSeal® and VIPER Tyton Sit.
VIPSeal® Flexible Couplings
As the pipe technology market has diversified, the range of materials sizes and designs has created ever more complex sealing challenges with no two installations being the same.
VIP-Polymers recognised this and responded to the market by innovating in the area of materials, design and full in-house engineering profiles with VIPSeal®
Designed to perform and engineered to last – VIPSeal® is a versatile range of flexible couplings and adaptors for joining and repairing low or non pressure pipes of any materials and size combination.
Manufactured at our state of the art UK facility, every product in the VIPSeal® range meets the requirements of UK and International Standards
About the range
Engineered for optimum resistance in most soil conditions, VIPSeal® heavy duty tension bands and shear bands are manufactured from 1.4301(304) austenitic stainless steel for general applications.For higher corrosion or contaminated ground areas and marine environments, grade 1.4401(316) stainless steel should be specified to eliminate the need for protective tape.
All VIPSeal® elastomeric sleeves are manufactured in-house using the highest quality raw materials to create the finest EPDM, SBR, NBR and FKM synthetic rubber.As such, the coupling sleeves offer excellent resistance to sewerage and drainage effluent. Where hydrocarbons, fats, oils or greases may be present, nitrile rubber (NBR) should be used. VIPSeal® also manufacture in FKM for applications where higher chemical resistance is required at special request. VIPSeal® rubber components are kitemarked in compliance with BS EN 681-1.
Pressure Resistance Correctly installed VIPSeal® couplings will withstand the following maximum pressures:Range Pressure up to Standard couplings with or without bushes (VSC/VBC) 2.5 bar Standard large and extra wide couplings with or without bushes (VLC/VLCW/VBC) 1.5 bar Standard extra wide couplings (VSCW) 2.5 bar Wraparound couplings (VWRC) 0.6 bar Drain couplings (VDC) 0.6 bar Adaptor couplings (VAC) 0.6 bar

Explanation of the VIPSeal family
The VIPSeal®Plumb range Is designed for connecting pipes with differing outside diameters for a smaller range of pipes in low or non-pressure plumbing applications.Consisting of couplings, adaptors, elbows, tees and end caps, they are manufactured from EPDM rubber, offering the same performance and temperature range operation as all other VIPSeal® products.
VIPSealPlus is manufactured from peroxide cured EPDM which is superior to the sulphur cured variant for elevated temperature applications and for applications that have to endure steam. Peroxide cured EPDM is recommended as continuous temperatures rise above 60⁰C for many years of leak free service is assured up to temperatures of 125⁰C. Peroxide cured EPMD has the same chemical compatibility as the standard VIPSeal range (sulphur cured EPDM).
VIPSealXtra is manufactured from sulphur cured Nitrile which is an effective material for applications that are exposed to mineral oils, fats and greases when constant temperatures remain below 60⁰C.
VIPSealXtraPlus is manufactured from peroxide cured Nitrile which is superior to the sulphur cured variant for elevated temperature applications.Peroxide cured Nitrile as continuous temperatures rise above 60⁰C for many years of leak free service is assured up to temperatures of 100⁰C.
VIPSealChem is manufactured from FKM which can cope with elevated continuous temperature applications up to 200°C. It’s resistance to a wide range of chemicals makes it the perfect choice for industrial and food applications.
VIPSealXtreme is manufactured from FFKM and is suitable for applications found in chemical and process industries. With a resistance to aggressive chemicals and CWT exceeding 200°C , VIPSealXtreme is designed for the toughest conditions.
