- • Best for: Plumbers and DIYers needing reliable mains isolation for MDPE-to-copper connections
- • Not ideal for: Systems that require non-compression fittings or non-standard pipe diameters
Compression connections link 20mm MDPE to 15mm copper as a reducing stopcock. WRAS and BS1010/BS EN1213 approvals confirm suitability for potable mains water.
Long-lasting durability – thanks to solid high-grade brass construction
Solid high-grade brass body resists corrosion and wears well under regular use, providing structural strength for threaded and compression joints. Brass also tolerates typical domestic water exposure without rapid degradation.
Durable brass minimises the need for early replacement, giving confidence for both indoor and outdoor installations. Reliable material choice reduces maintenance for household and commercial fittings.
Quick, solder-free installation – with compression inlet and outlet connections
Compression fittings seal by compressing a ring around the pipe when the nut is tightened, creating a watertight joint without soldering or specialist tools. Suitable for standard copper and MDPE pipe ends when correctly prepared.
Fast installation makes on-site work quicker and reduces tool requirements for tradespeople and competent DIYers. A simple compression fit is practical for repair, replacement, and new mains connections.
Safe for drinking water – thanks to WRAS, BS1010 and BS EN1213 approvals
Approvals indicate compliance with UK standards for materials and performance in potable water systems, including tests for leaching and mechanical reliability. Certification supports use across domestic mains installations.
Certified suitability for potable water reassures installers and homeowners when isolating mains or connecting outdoor taps. Standards compliance supports acceptance in regulated plumbing projects.
