Zoro Select 1RTL1 1/2 in 316 Stainless Steel Square Head Plug Male NPT Class 3000

SKU CH-JQVG-1FHZ4

Stainless steel 316 square-head plug seals 1/2 inch male NPT threads, rated 3000 psi at 100°F and 2500 psi steam at 350°F per ASME B16.11 Class 3000 and ASTM A182

  • 316 stainless steel resists corrosion in harsh environments
  • Male NPT threads seal pipes to 3000 psi at 100 °F
  • Square head allows high-torque installation with a wrench
  • Meets ASME B16.11 Class 3000 for reliable pressure containment
  • ANSI/ASME B1.20.1 threads ensure compatibility with standard fittings

1/2 in 316 Stainless Steel Square Head Plug

The Zoro Select 1RTL1 is a 1/2 inch nominal pipe size plug made from 316 stainless steel that conforms to ASTM A182 standards. It features a male National Pipe Thread connection built to ANSI/ASME B1.20.1 thread standards. The fitting meets ASME B16.11 Class 3000 pressure class requirements for industrial piping systems.

Suitable Applications and Limitations

This plug suits installers terminating threaded pipe, couplings, or fittings in high-pressure water, oil, or gas lines where 316 stainless corrosion resistance is required. It is rated for 3000 psi at 100°F and 2500 psi steam pressure at 350°F. Buyers needing a different nominal size, thread standard, or pressure class should select an alternative fitting. No thread sealant is included.

Deciding Specification

The defining specification is the Class 3000 pressure rating per ASME B16.11 combined with 316 stainless steel material. This rating confirms the plug handles 3000 psi at 100°F and 2500 psi saturated steam at 350°F. Verify that your system design pressure and temperature fall within these limits before installation.

Questions about this item

What does the 3000 psi rating mean when the plug is installed in a piping system?

The 3000 psi rating is the maximum allowable non-shock pressure at 100°F for the Class 3000 fitting under ASME B16.11.

How does the Male NPT thread standard affect sealing and compatibility?

The ANSI/ASME B1.20.1 taper threads require sealant or tape to seal; they mate with any female NPT fitting of the same nominal size.

What size wrench or socket is needed to install the square head?

The square head accepts a standard 1/2 inch drive or wrench sized for a 1/2 inch NPT plug.
