3/8 inch x 1/2 inch Sharkbite Push Fitting Reducing Coupling

3/8" x 1/2" OD Push-Fit Reducing Coupling – Lead-Free Brass Fitting for PEX, Copper, and CPVC

This 3/8" x 1/2" OD Push-Fit Reducing Coupling provides a mechanical connection between dissimilar pipe sizes without the need for soldering, gluing, or crimping. Designed to join 3/8" pipe to 1/2" (OD) tubing, this fitting supports a wide range of low- and moderate-pressure plumbing applications, including potable water distribution and fixture branch lines.

Engineered for compatibility with PEX, copper, CPVC, PE-RT, and HDPE, this push-to-connect fitting uses an integrated O-ring and stainless steel grab ring to achieve a secure and reusable seal. The compact design allows for fast connections in limited-access locations without the need for special tools.

Contractor-Focused Benefits

• ✅ Tool-Free Installation Push-fit ends eliminate the need for heat, adhesives, or crimp tools on the jobsite.
• ✅ Reusable Design Detachable with a disconnect clip or tongs, allowing for system reconfiguration during layout changes or service.
• ✅ Certified Lead-Free Complies with NSF/ANSI 61 and 372 for potable water systems under federal lead content requirements.
• ✅ High-Pressure Rated Suitable for up to 200 PSI and 200°F, depending on the piping material used.

Installation Guidance

Verify tubing is clean, round, and cut square. Use a depth gauge and mark the insertion line. Insert the pipe into the fitting until it reaches the tube stop. For disconnecting, use an approved demount clip or tong per manufacturer's specification. Follow all applicable plumbing codes, especially when transitioning between materials or integrating with pressurized systems.

Common Applications

Frequently used in fixture branch lines, manifold systems, and remodels involving copper-to-PEX transitions. Especially effective in confined spaces where torch work or crimp tools are impractical. Ideal for emergency repair situations and system extensions in residential and light commercial installations.

System Compliance Note

This push-fit coupling is approved for use in underground and behind-wall applications without access panels when installed per applicable codes and with manufacturer-recommended pipe supports.

The 3/8" x 1/2" OD Push-Fit Reducing Coupling offers field-proven reliability, dimensional accuracy, and compliance with potable system standards—making it a preferred solution for contractors seeking time-saving, code-compliant installations across multiple piping systems.
