Uniweld Sales Executive, Matt Foster, demonstrates how to rebuild Uniweld’s EZ-Turn™ Anti-Blowback fittings which are engineered for on-site repairs. Over time, aggressive refrigerants and P.O.E oils will deteriorate the rubber gaskets and O-Rings and they will need to be replaced. All internal parts are replaceable and come in a rebuild kit, Part# EZHRK, sold separately.
