Value Brand Straight Coupling 1/2" NPT x 3/8" NPT Class 150

SKU CH-MKV6-Y1YZM

Malleable iron straight coupling connects 1/2" and 3/8" female NPT threads at Class 150 rating

  • Malleable iron construction delivers durable corrosion resistance
  • Class 150 rating supports standard pressure requirements
  • 1/2" NPT to 3/8" NPT female threads enable pipe reduction
  • Galvanized finish protects against rust and wear
  • New condition ensures reliable out-of-box performance

Straight Coupling 1/2" NPT x 3/8" NPT

This malleable iron coupling connects a half-inch NPT female thread to a three-eighths NPT female thread. It is rated for Class 150 service and suits plumbing or compressed-air lines that need a straight, rigid joint.

Check thread size and pressure rating

Verify that both pipe ends carry the exact NPT sizes shown and that the system pressure stays within the Class 150 limit. Confirm the galvanised malleable iron is compatible with the fluid or gas being carried and note the Proposition 65 warning for California installations.

Fits between two female-threaded components

The coupling joins a 1/2 inch port to a 3/8 inch port without changing direction, reducing the need for a separate reducer and nipple. It requires thread sealant or tape on both ends and frees up space compared with a multi-piece assembly.

Questions about this item

What is included with the straight coupling and are any additional fittings required?

The box contains the malleable iron straight coupling with 1/2" and 3/8" female NPT threads; pipe sealant or tape for the threaded joints must be purchased separately.

How do I decide between the available versions of this Class 150 coupling?

This listing offers a single configuration — 1/2" NPT by 3/8" NPT galvanised malleable iron — so no version choice is needed.

What does the Class 150 rating mean for pressure handling in a typical installation?

Class 150 indicates the fitting is rated for 150 psi working pressure at ambient temperature in standard water, oil or air service.
