1 inch PEX Ring with Stop

1 inch PEX Ring with Stop – ASTM F1807 Crimp Fitting Accessory

The 1 inch PEX ring with stop is a crimp-style connection component used in joining cross-linked polyethylene (PEX) tubing to brass or poly-alloy fittings. Designed with an internal stop to control tubing insertion depth, this component supports consistent and secure connections in pressure-rated potable water and hydronic systems.

Manufactured to ASTM F1807 or F2159 specifications (depending on material), the ring is typically constructed from lead-free copper or stainless steel and is compatible with standard PEX crimp tools. It enables installers to maintain uniformity and code compliance across PEX plumbing installations.

Performance Features

• ✅ Size: 1 inch nominal PEX tubing diameter
• ✅ Integrated Stop: Prevents over-insertion of PEX tubing and ensures consistent sealing position
• ✅ Material: Lead-free copper, stainless steel, or engineered polymer (varies by spec)
• ✅ Connection Type: Crimp ring – compatible with ASTM F1807/F2159 fittings and ASTM F876 PEX tubing
• ✅ Tool Compatibility: Installs using standard PEX crimp tools with go/no-go gauge verification

Installation Guidelines

Proper installation requires placing the ring over the PEX tubing, positioning it against the fitting shoulder, and compressing it using an ASTM-compliant crimp tool. Visual inspection and verification with a go/no-go gauge are recommended for ensuring joint integrity. Follow local code and manufacturer instructions for tooling and spacing tolerances.

Typical Use Cases

This component is used in residential and light commercial potable water distribution, radiant heating, and snow melt systems. It is specified where PEX-to-fitting transitions require mechanical sealing through a compression ring. Its stop feature helps minimize errors during fast-paced or repetitive installations.

Regulatory Compliance

Lead-free construction meets U.S. Safe Drinking Water Act (SDWA) requirements and is certified under NSF/ANSI 61 and NSF/ANSI 372 for use in potable water systems. The product also complies with IPC and UPC installation standards where applicable.
