Primofit Adaptor 3/4" BSPM x 25mm MDPE for GRP Sleeve (Wall Mounted)
At a building entry point or service connection, transitioning yellow MDPE gas pipe onto BSP threaded steel calls for a fitting that seals reliably without welding or heat fusion — which is exactly what this George Fischer Primofit compression adaptor is built for. The ¾" BSP male end connects to steel pipe or fittings, while the compression end grips 25mm yellow MDPE pipe mechanically, with insert stiffeners supplied to maintain the pipe bore at the compression point.
The galvanised malleable iron body meets BS EN 10255 and BS EN 10220, and accepts a GRP sleeve for wall-penetration or bracket-mounted installations where the transition needs extra physical protection. The fitting carries a 7 bar rating at 20°C — worth noting that the actual maximum operating pressure in a given installation also depends on the specification of the MDPE pipe used, not the fitting alone. 6° of angular deflection allows for slight misalignment in the pipe run during installation.

Compression Fitting, No Welding Required: Mechanical grip on the MDPE pipe without heat fusion tools.
6° Angular Deflection: Accommodates slight pipe misalignment at the transition point.
Galvanised Malleable Iron Body: Corrosion-resistant for external and exposed installations.
Accepts GRP Sleeve: For wall-mounted installations requiring mechanical protection of the fitting.
Insert Stiffeners Included: Maintains the MDPE pipe bore at the compression end.
Ideal For
Connecting 25mm yellow MDPE gas pipe to ¾" BSP male steel pipe at building entry points.
Service connection terminations for residential, commercial, and industrial gas supply.
Gas Safe registered engineers installing or replacing MDPE-to-steel gas transitions.
Why Buy This Product?
Building entry and service connection transitions are exactly the kind of joint you want done once and done right — this genuine GF Primofit fitting gives you a compliant, leak-free MDPE-to-steel connection without welding, and the GRP sleeve compatibility means the fitting is properly protected once it's behind a wall or bracket rather than left exposed.
