Hep2O adaptors are assembled and manufactured in the UK from solid brass for a durable and professional quality fitting. This equipment has a perfect grip seal which helps connect soil and waste pipes together. Joints in the ring seal system are push-fit. The joint is made pushing the end of a lubricated, chamfered pipe squarely into the fitting, which compresses the equipment to make an airtight and watertight joint. It is a reliable and trouble-free leakproof plumbing device.
