  • Reduces pipe size with 1/4 in x 1/8 in FNPT connection
  • Handles 300 psi at 150 °F for reliable pressure containment
  • Meets ASME B 16.3 and B 16.4 standards for quality assurance
  • FM Approved and UL Listed for verified safety compliance
  • Operates from -20 °F to 366 °F across diverse temperature conditions

Reducer coupling for small-bore pipe

The Value Brand malleable-iron reducer coupling joins a 1/4 inch female NPT line to a 1/8 inch female NPT line in plumbing and compressed-air systems. It meets ASME B 16.3 and B 16.4 standards and carries FM and UL listings for code-compliant installations.

Class 150 iron body with FNPT threads

The Class 150 malleable-iron casting withstands 300 psi at 150 degrees F and 150 psi saturated steam across a -20 to 366 degrees F range. FNPT threads on both ends allow direct assembly with standard pipe nipples without soldering or special tools.

ASTM-grade material and dual certification

Produced to ASTM A-197 and ASTM A47 specifications, the fitting resists cracking under thermal cycling and vibration. The FM Approved and UL Listed marks let inspectors accept the joint in fire-protection and general-service piping without additional documentation.

Questions about this item

What pressure and temperature limits does the Class 150 malleable iron reducer coupling handle?

Rated for 300 psi at 150 °F and 150 psi saturated steam, with an operating range from -20 °F to 366 °F.

Which pipe-thread standard do the 1/4 in and 1/8 in FNPT ends follow?

The female NPT threads conform to ASME B 16.3 and B 16.4 for taper pipe threads.

How do you seal the FNPT threads without cracking the malleable iron fitting?

Apply PTFE tape or pipe dope to the male threads only, hand-tighten, then turn one to two full turns with a wrench — over-tightening is the common mistake.
