SKU CH-DPRK-PYVPD

A malleable iron straight coupling joins two 1/8 inch NPT female threads at Class 150 pressure rating

  • Malleable iron construction resists cracking under pressure
  • Galvanised finish protects against corrosion in wet systems
  • Class 150 rating suits standard low-pressure plumbing
  • 1/8 NPT female threads connect directly to matching pipe
  • California Proposition 65 notice informs safe handling practices

1/8 NPT Malleable Iron Coupling

This galvanised malleable iron coupling connects two sections of 1/8 inch NPT female pipe threads. It is rated to Class 150 pressure service and carries the ZORO SELECT brand. The fitting meets standard pipe threading dimensions for secure, leak-resistant joints in plumbing and compressed air systems. It is supplied new and ready for installation.

For threaded pipe connections only

This coupling suits installers joining two male-threaded pipes or nipples of the same 1/8 NPT size in water, air or inert gas lines. It will not fit BSP, metric or larger NPT threads, and it cannot be used where a reducing coupling or a different material such as brass or stainless steel is required. Buyers needing a different thread standard or a higher pressure class should look elsewhere.

Class 150 pressure rating

The Class 150 designation defines the maximum working pressure for this malleable iron fitting at standard temperatures. This single rating determines whether the coupling is appropriate for the intended system pressure. Verify the system design pressure against the Class 150 limit before purchase. The product also carries a California Proposition 65 warning for listed chemicals.

Questions about this item

What does the Class 150 rating mean for everyday plumbing use?

Class 150 indicates the maximum working pressure this malleable iron coupling is designed to handle in standard installations.

How does the 1/8 NPT thread standard affect compatibility with other fittings?

The 1/8 NPT threads follow the National Pipe Taper standard, creating a seal through thread engagement with matching male NPT fittings.

What are the physical dimensions needed to fit this coupling into a pipe run?

Each end measures 1/8 inch female NPT with 27 threads per inch, requiring male NPT pipe or nipples of the same size to connect.
