Gerpex Press Fittings are WRAS approved when use in conjunction with TH profile pressing jaws. However the fittings are fully compatible with B profile up to 32mm and U, H & F up to 20mm sizes.
B, U, H & F profiles don’t have the WRAS approval with Gerpex Press Fittings so please check potable water requirements for the project with the architect, project manager, etc as appropriate before using these jaw profiles.
