Rubber Pipe Connectors & Flexible Adaptors

Flexible rubber couplings and adaptors are an easy way to join two lengths of pipes with a different diameter, for example plastic to clay, or plastic to cast iron. They simply fit over each end of the pipe and are tightened with a stainless steel jubilee clip to create a watertight seal.

Fitting rubber pipe connectors

These flexible rubber connectors are designed to simplify the installation and repair of Flex and Rigid PVC piping. Also used for joining drain, waste and vent lengths. Expert design and ISO 9000 quality system ensure quality without compromise. Flexible connectors carry a lifetime limited manufacturer's warranty.

Flexible Adaptor Couplings are made to join pipework together where there's a difference in outside diameter. The adaptor couplers have a stepped moulded elastomeric sleeve with different diameters at either end to allow pipes of varying diameters to be joined and quickly without the need for bushes. The sleeve is fitted with two stainless steel rings by which they clamp to the end of each plain section.

Flexible Drain Rubber Couplings are used predominantly in sewage, sewer and other non-pressure software to combine any material and diameter. The outer steel clamps provide a leak proof seal on any pipe material whether the surface is smooth or rough. On stacks where the diameters vary, bushes can be inserted to improve the diameters of the pipe prior to joining. Where the difference in diameter exceeds 12mm a bush should always be used if a suitable adaptor is not available.

EasyMerchant provides a variety of Standard Couplings - parts which have revolutionised pipe repair methods through the years.

Flexible Rubber Couplings from EasyMerchant are designed to join pipework of different materials or sizes used in sewerage, drainage and other underground applications. When excavation work must repair a pipe, EasyMerchant's Rubber Couplings will decrease the amount of time required and minor alterations in diameter can be easily accommodated.

The combination of a durable design and excellent sealing properties when tightened to the correct torque enable the rubber coupling to form a reliable seal on demanding pipe surfaces e.g. concrete, as well as on smooth surfaces e.g. plastic.

Rubber Couplings can be combined with bushes in order to serve as an adaptor between runs of differing diameters. EasyMerchant's Flexible Couplings are made from EN681-1 EPDM rubber and have Grade 1.4301 (304) stainless steel clamps and shear bands. EasyMerchant can supply the product with nitrile sleeves for use. Couplings are also available with Grade 1.4401 (316) stainless for enhanced corrosion protection.
