Clesse EvoFit Meterbox Transition Fitting 3/4 BSP Male x 25mm MDPE (UU25MMX3/4TFK) Installing a gas meter box connection usually means sourcing a transition fitting, an isolation valve, and a test point separately — the Clesse EvoFit combines all three into one compact unit. The mechanical compression fitting makes a safe, leak-free transition between 25mm MDPE pipe and ¾ BSP threaded equipment, with no heat fusion tooling required on site. Built into the same unit is a MOP 5 ball valve compliant with EN 331, giving a proper isolation point to safely control gas supply, along with a factory-fitted test point complete with a 1/8 Schrader valve and protective cap for commissioning and testing. The nickel-plated brass construction and conical nitrile rubber seal (tested to EN 682) are built for long service life, and the whole assembly meets EN 15
