PVC × HDPE Transition Fitting | IPS | Schedule 80 | Series 735

PVC × HDPE Transition Fitting | IPS | Schedule 80 Coupling | Series 735 Reliable PVC-to-HDPE transition for IPS-sized HDPE. The Series 735 joins a Schedule 80 PVC coupling to IPS (Iron Pipe Size) HDPE pipe with a hydraulically pressed, multi-level barb joint locked by a stainless-steel (or PVC) ID insert — a permanent, leak-free connection for pressure and conduit systems. Key Features Leak-Free Joint: Multi-level barb system and ID insert form a tight radial compression seal. Insert Options: PVC, 304 stainless, or 316 stainless ID insert — stainless steel is standard, PVC available. Durable Materials: Schedule 80 PVC coupling (ASTM D1784), HDPE pipe (ASTM F714 / D3350, PE4710 / PE3408). Full Pressure Rating: Matches the HDPE pipe’s pressure class with a 2:1 safety factor at 73°F and a 50-year design life. Certified: NSF/ANSI 61 (listing PM19359), ARRA compliant, made in the USA. IPS Sizing: IPS (Iron Pipe Size) HDPE, ¾" through 6", in SDR 9 and SDR 11.
