Standard Female NPT Transition Fitting | IPS | SDR 11 | 200 PSI
Integrity Fusion’s Standard Female NPT (FIPT) Transition Fitting is engineered for secure, corrosion-resistant connections between HDPE piping and threaded steel systems. Designed for IPS SDR 11 pipe and rated for 200 PSI (MAOP @ 73.4°F), this fitting combines strength, reliability, and long-term performance in demanding utility and industrial applications.
Constructed from high-quality ASTM A53/API-5 carbon steel or optional 304/316 stainless steel, each fitting features an internally machined and beveled groove that forms a robust mechanical joint with the HDPE pipe. The full internal HDPE extension ensures an unobstructed, piggable flow path while providing total corrosion protection and restraint against thermal expansion forces.
This transition fitting meets or exceeds multiple industry standards, including ASTM D3261, ASTM D1598, D1599, ANSI/AWWA C901, C906, and NSF/ANSI/CAN-61 & 372. It is heat-fusible with all compatible PE3408, PE4710, and PE100 HDPE piping systems.
Note: This fitting is not for natural gas service. Installation requires the use of strap wrenches only—do not use pipe wrenches to avoid damaging the seal.
Key Features:
- Female NPT (FIPT) end for ANSI/ASME B1.20.1 threaded steel pipe connection
