We offer a full range of Mech branded flexible grooved couplings from Jinan Meide, this includes sizes 1" - 16" as well as red-oxide primer painted, HDG galvanised and epoxy white finishes. Flexible coupling use EPDM gaskets and force applied by the included steel bolts & hex nuts to create a tight seal between grooved pipe or fittings, this type of coupling allows for linear & angular movement as well as thermal expansion or contraction. We also offer a small range of flexible reducing couplings.
These ductile iron couplings are often used in fire protection systems and come with a variety of relevant approvals include FM, UL, LPC & VdS, they’re also BSI Kitemarked. 1N flexible couplings are up to 34.5 bar (500 PSI) pressure rated and can be installed without any hot working or specialised tools, grooved lubricant should be used (available separately).
