Speedfit 28mm Superseal Pipe Insert STS28 (Pack of 10)

The Speedfit 28mm Superseal Pipe Insert STS28 strengthens and seals Speedfit pipe connections with advanced dual O-Ring technology. Designed to maintain pipe shape and ensure structural integrity, this insert prevents leaks and supports secure installations in hot and cold water systems, as well as central heating. Exclusively for Speedfit pipes and fittings, the WRAS approved STS28 provides superior performance and peace of mind.

The JG Speedfit 28mm Superseal Pipe Insert STS28 delivers an advanced sealing solution for Speedfit push-fit systems, offering increased rigidity and security. Fitted with two O-Rings, the insert forms a dual-action seal that provides superior leak protection. The first O-Ring, located on the stem, prevents water from travelling between the pipe and insert, while the second O-Ring at the tip forms a seal within the fitting itself. When used with Speedfit push-fit fittings, which feature their own built-in O-Ring, the result is a dependable multi-seal system. This insert also reinforces the pipe’s structural integrity by supporting its shape and helping it withstand side loads. Suitable for both domestic and commercial plumbing, it is compatible only with Speedfit pipes and fittings and is WRAS approved for quality assurance. The STS28 is ideal for hot and cold water supply and central heating applications.
