O-SEAL MALE CONNECTOR - NPT
O-SEAL MALE CONNECTOR - NPT
The O-Seal Male Connector – NPT is designed for leak-tight, high-pressure connections in piping and instrumentation systems using NPT (National Pipe Tapered) threads. This connector features an integrated O-ring seal at the face of the fitting, providing a secondary sealing mechanism that ensures superior leak protection, even under high-pressure and vibration conditions. Available in sizes ranging from 1/8” to 2” (imperial) and 3mm to 50mm (metric), it supports a wide range of applications across industries. Manufactured from high-grade materials such as Stainless Steel (SS), Brass, Duplex, Monel, and Hastelloy, the O-Seal Male Connector offers outstanding corrosion resistance and durability. It is ideal for critical systems where leak prevention is essential, such as hydraulic, pneumatic, chemical, and oil & gas applications.
