1 Inch x 3/4 Inch PEX Brass Reducing Insert Coupling – Crimp x Crimp

The 1 Inch x 3/4 Inch PEX Brass Reducing Insert Coupling is engineered for use in potable water distribution systems, providing a transition between differing PEX tubing sizes. Designed for ASTM F1807 crimp applications, this fitting supports a secure mechanical connection using copper crimp rings or stainless steel clamp rings in accordance with industry standards.

Application and Material Details

  • Material: Machined from lead-free dezincification-resistant brass (DZR), compliant with NSF/ANSI 61 and 372
  • Connection Type: Crimp x Crimp for SDR9 PEX tubing
  • Typical Use: Residential and commercial water supply lines where a size transition is required

Product Advantages

  • Dimensional Precision: Machined barbs are held to tight tolerances to ensure leak-free compression during the crimp process
  • Corrosion Resistance: Brass alloy provides long service life in hot and cold water applications
  • Code Compliant: Listed to ASTM F1807 and compatible with PEX systems conforming to CSA B137.5

Installation Guidelines

For optimal performance, install using a calibrated crimping or clamping tool approved for ASTM F1807 or F2098 connections. Ensure crimp rings are centered and properly positioned over the barbed ends before securing. Joints must be pressure-tested after installation to verify system integrity.

Specifications

  • Main Size: 1 inch
  • Reduced Size: 3/4 inch
  • Pressure Rating: 160 psi at 73°F, 100 psi at 180°F
  • Certifications: ASTM F1807, F877; NSF/ANSI 61 & 372; CSA B137.5

Typical Applications

Commonly installed in branch line transitions, manifold assemblies, and retrofit situations requiring a reduction in PEX tubing diameter. Suitable for both hot and cold water service.

Industry Note

As of 2014, all potable water system fittings in the United States must be certified lead-free. This coupling conforms to federal lead-free legislation and is third-party tested for compliance.
