3/4 inch x 1/2 inch Sharkbite Push Fitting Straight Reducing Coupling

3/4" x 1/2" Push-Fit Reducing Coupling – Brass Transition Fitting

This 3/4" x 1/2" push-fit reducing coupling is manufactured for rapid, tool-free installation of copper, CPVC, or PEX tubing. The fitting enables a reliable transition between dissimilar pipe sizes while maintaining code-compliant integrity under typical residential and light commercial plumbing conditions.

Constructed from DZR (dezincification-resistant) lead-free brass, the coupling features internal stainless steel grab rings and EPDM O-rings for a secure, watertight seal upon insertion. It is approved for use in potable water systems and rated for continuous pressure applications.

Features and Advantages

• Push-to-Connect Technology: No crimping, soldering, or gluing required—ensures a clean installation in tight or confined spaces.
• Dual Material Compatibility: Suitable for copper, PEX, and CPVC tubing (CTS-sized)
• Built-In Demount Capability: Allows disconnection with a dedicated removal tool or clip for system flexibility
• Lead-Free Brass Body: Conforms to ANSI/NSF 61 and 372 for potable water applications
• Corrosion-Resistant Construction: Internal components resist scaling and degradation in domestic water environments

Technical Specifications

• Connection Size: 3/4" CTS x 1/2" CTS
• Material: DZR Lead-Free Brass
• Seal Material: EPDM O-ring
• Maximum Working Pressure: 200 PSI
• Maximum Temperature: 200°F
• Certifications: ASSE 1061, NSF/ANSI 61 & 372, UPC, IPC, and CSA B125.3

Applications

Primarily used in residential water distribution systems and branch line repairs or additions, this push-fit coupling supports direct transition between differing pipe diameters. It is commonly deployed in potable cold and hot water plumbing, including retrofit conditions where access to pipes is limited or flame-based joining is prohibited.

Additional Considerations

This fitting is reusable and may be rotated after installation. Always verify tubing is properly deburred and inserted to full depth to maintain pressure seal integrity. For permanent connections, use pipe locking clips where required by local code.

Engineered for code compliance and field efficiency, this 3/4" x 1/2" push-fit coupling provides durable performance without compromising installation speed. It’s a practical solution for professional plumbers managing time-sensitive repairs or installations in variable system configurations.
