Description
1/2 in PEX x 3/4 in MPT Adapter
The 1/2 in PEX x 3/4 in MPT Adapter is a reducing PEX fitting used to connect a 1/2 in PEX line to a 3/4 in male pipe-thread port. Plumbers and mechanical contractors use reducing adapters for equipment tie-ins, valve connections, and retrofit situations where the PEX line size differs from the threaded component size.
Key Features & Installation Benefits
– Reducing transition: Connects mismatched line sizes without unnecessary extra fittings.
– Cleaner tie-in: Helps keep layouts simple and serviceable.
– Common retrofit solution: Useful in renovations and equipment replacements.
Common Applications
Threaded shut-off valves, equipment ports, manifolds, and other threaded connections that require 3/4 in male thread while the PEX run remains 1/2 in.
Before Ordering
Confirm thread standard (PT/NPT as applicable). Match your PEX connection method (crimp, clamp, or press) and verify sizing, flow requirements, and local plumbing code compliance.
