This bulk 10-pack of lead free brass reducing couplings steps 1/2" PEX tubing down to 3/8" PEX per fitting. The bulk quantity keeps larger jobs moving without running short on size-transition fittings for branch step-downs, manifold-to-fixture transitions, and PEX-to-polybutylene conversions.

• Lead free brass construction certified safe for potable drinking water (meets the 0.25% lead-content rule per the Reduction of Lead in Drinking Water Act)
• Reduces from 1/2" PEX to 3/8" PEX in one straight fitting
• Works on hot and cold water supply, hydronic radiant heat, and PEX-to-polybutylene transitions
• Compatible with standard PEX tubing brands (Uponor, Viega, SharkBite, Apollo, Zurn, Watts)
• Crimps with copper rings per ASTM F1807 or stainless cinch clamps per ASTM F2098 (use the ring sized for the matching tubing OD on each side)
• Brass body resists corrosion, mineral scale, and pipe-stress cracking far better than push-fit plastic alternatives
• 10 reducing couplings per bag for contractor-grade jobsite stock

Tip: A reducing coupling has two different barb diameters - confirm which side is which before cutting your tubing. Cut PEX square with a dedicated PEX cutter, slide the correctly-sized crimp ring or cinch clamp onto each side (1/2" ring for the 1/2" side, 3/8" ring for the 3/8" side), push each tubing end fully onto its barb until it bottoms out, then crimp roughly 1/8" to 1/4" from the end. Verify each crimp with a go/no-go gauge before pressure-testing.
