Couplet Coupling

multiflex coupling is designed to conveniently join pipes together without the need of welding, grooving and threading of pipes. The multiflex coupling allows for the pipes to be securely fastened under pressure for a variety of situations and uses. It comes in a number of diameters and sizes for maximum versatility. If you have interests in our multiflex coupling, check our website or contact us for more information of multiflex coupling
