Proline 1/2" FIP CPVC Transition Adapter 164-313NL

SKU CH-EZQF-1T249

Connects 1/2 in CPVC pipe to brass FNPT threads, rated 200 psi and compliant with NSF/ANSI 61 and AB1953

  • CPVC-to-brass transition simplifies mixed-material plumbing
  • 200 psi rating handles typical residential supply pressures
  • NSF/ANSI 61 certified for safe potable-water contact
  • ANSI B168 and CSA listed for code-compliant installations
  • AB1953 compliant lead-free brass meets strict health standards

Product Identity

This CPVC-to-brass transition adapter connects 1/2-inch CPVC piping to female NPT threads. It serves plumbers and maintenance teams joining dissimilar pipe materials in potable-water systems.

What the Standards Change

Compliance with ANSI B168, NSF/ANSI 61, CSA, FM and UL allows use in drinking-water installations. The AB1953 listing confirms lead-free construction for regulated jurisdictions. A 200 psi pressure rating supports typical residential and light-commercial service.

Installation Notes

The socket-by-FNPT design requires solvent-cement on the CPVC side and thread sealant on the brass side. Over-tightening the brass threads can crack the CPVC hub. Verify local code acceptance before assembly.

Questions about this item

Will the brass threads on the 164-313NL need replacement due to dezincification over time?

The adapter complies with AB1953 and NSF/ANSI 61, meaning the brass meets low-lead and dezincification-resistant standards for potable water.

At what pressure will the CPVC socket on this 1/2 in adapter reach its limit during sustained use?

The maximum working pressure is rated at 200 psi, which is the primary limit for the CPVC socket connection under continuous load.

Does the brass body on the 164-313NL transfer enough heat to affect CPVC cement joints during all-day hot water circulation?

Brass conducts heat more than plastic, but the 1 in outside diameter provides sufficient mass to keep joint temperatures within CPVC cement limits for standard hot water temperatures.
