Stainless Steel Fitting Hex Head Plug B16.11 Hexagon ASME SA105 Class 3000

Stainless Steel Fitting Hex Head Plug B16.11 Hexagon ASME SA105 Class 3000

A plug is a solid fitting with male threads that screws into a female opening to close it . The hex head allows it to be easily tightened or removed with a standard wrench or socket . The stainless steel material provides strong resistance to corrosion from water, heat, saltwater, and many chemicals .

Common Applications

Because it's robust and corrosion-resistant, this plug is used across many demanding industries to seal or blank off pipe ends and unused ports. Typical applications include :

Oil, gas, and petrochemical pipelines, where it's used to close idle branch connections or instrument taps.

Chemical processing plants, for sealing lines carrying corrosive fluids.

Power generation, for sealing vents, drains, or unused ports.

Hydraulic systems, where it blocks off pressure ports.

General industrial use, for permanently or temporarily sealing openings during testing, maintenance, or decommissioning.

Key Features of This Fitting

Connection Type: It features a Male NPT (National Pipe Taper) thread. The tapered design creates a tight, leak-resistant seal when screwed into a female fitting .

Pressure Range: Class 3000 fittings are intended for high-pressure systems, typically operating in the 1,000-3,000 psi range .

Material: ASME SA105 is a common specification for forged carbon steel used in high-temperature and high-pressure services, often with a black anti-rust coating .
