Black Forged Steel Merchant Coupling Class 300

This Anvil 0320201064 coupling connects two 1 1/4 inch female NPT pipes in Schedule 80 systems. It is built for plumbers and maintenance crews who need a reliable threaded joint in black forged steel.

Class 300 pressure rating

Rated Class 300, the fitting handles up to 500 psi at 150 degrees Fahrenheit in normal service. The forged steel construction resists deformation under steady pressure and temperature cycles typical of commercial plumbing.

Sustained load performance in Schedule 80 piping

Under continuous pressure at the rated limit the coupling maintains seal integrity without leakage. It is not intended for applications exceeding Class 300 or for pipe schedules other than Schedule 80.

Questions about this item

How do I install the 1 1/4 in NPT female threads without cross-threading?

Clean both threads, apply PTFE tape or pipe dope to the male end only, then hand-tighten until resistance is felt before using a wrench for one to two full turns; over-tightening distorts the forged steel seat.

What maintenance does the Class 300 forged steel coupling require over time?

Inspect the joint annually for weeping or corrosion; re-apply thread sealant if a drip appears, and replace the coupling if the NPT threads show galling or the body cracks from thermal cycling.

At what temperature does the 500 psi pressure rating reach its limit during continuous service?

The 500 psi maximum operating pressure is rated at 150 Degrees F; sustained temperatures above that reduce the allowable pressure for the Schedule 80 forged steel body.
