Adaptors mate 16mm pipe to 15mm compression fittings using precision-engineered seals. Compact form fits into tight installation spaces for domestic and commercial plumbing.


Secure, leak-free joints – Thanks to precision compression seal

Precision-engineered components compress against the mating surfaces to form a tight seal under pressure. The design reduces gaps where water could escape and resists loosening during thermal cycling.

A reliable seal reduces the risk of water loss and damage, making the adaptors suitable for visible pipework and radiator connections. Fewer call-outs for leaks mean less disruption over time.

Fast, tool-light installation – With straightforward compression fittings

Fittings are designed for quick assembly without specialised tools, relying on standard compression assembly steps rather than specialist equipment. Compact geometry aids access in confined cavities.

Installation time is shorter for both DIY and trade users, and jobs in tight cupboards or behind radiators become simpler. Contractors can fit multiple adaptors quickly during routine maintenance.

Broad system compatibility – With 16mm to 15mm cross-size connections

Geometry and tolerances match common 16mm pipe and 15mm compression interfaces, making the adaptors suitable across several supply types. Materials are chosen to handle typical plumbing pressures.

Useful for hot and cold water supplies as well as heating circuits, enabling straightforward repairs or modifications. A single adaptor type handles multiple common scenarios on the job.
