1 in x 3/4 in PEX Reducing Coupling
The 1 in x 3/4 in PEX Reducing Coupling is a reducing PEX fitting used to transition from 1 in PEX to 3/4 in PEX in a straight, inline connection. Contractors use reducing couplings to step down line size cleanly when moving from a main distribution run to a smaller branch line, without stacking multiple adapters.
Key Features & Installation Benefits
– Single-fitting reduction: Simplifies layouts and reduces potential leak points.
– Distribution-to-branch transition: Ideal when stepping down from mains to branches.
– Service-friendly: Keeps the transition neat and accessible for maintenance.
Common Applications
Reducing from 1 in PEX mains or headers to 3/4 in distribution branches in residential and light commercial plumbing.
