Compression nut with washer and ring 1/2" AGAflex 42100724

Compression nut with washer and ring 1/2" AGAflex 42100724 is a mechanical connection component intended for securing and sealing 1/2" pipe joints in plumbing and heating systems. The assembly includes a compression nut, an integrated washer and a retaining ring designed to create a reliable seal at threaded connections and to maintain mechanical stability between tubing and fittings. It is compatible with systems that accept 1/2" compression fittings and is suitable for use in both residential and commercial installations where a compact, serviceable joint is required.

Advantages

The compression nut with integrated washer and retaining ring provides a straightforward installation process without the need for soldering or adhesives. Its design concentrates sealing and retention functions into a single part, which reduces the number of separate components to handle and simplifies maintenance. The unit supports leak-resistant threaded joints when installed according to manufacturer guidelines and enables disassembly and reassembly for repairs or modifications.

Suitable for

• Securing 1/2" copper, stainless steel or compatible tubing to compression fittings
• Domestic plumbing connections such as sinks, faucets and under-sink supply lines
• Heating system connections including radiators and circulator pump fittings
• Commercial plumbing installations where compact, serviceable joints are required

Key specifications

• Connection size: 1/2" compatible compression fitting
• Includes: compression nut, integrated washer and retaining ring
• Application: mechanical sealing of threaded or compression joints
• Typical materials: metal nut with washer and ring suitable for plumbing use
• Installation type: push-on/hand-tightenable with final torque using appropriate tools

How to use

Prepare the tube end by ensuring it is cut square, deburred and clean of debris. Slide the compression nut and washer onto the tube in the correct order, then insert the tube into the mating fitting until it seats against the fitting stop. Hand-tighten the compression nut and, where specified, use a wrench to apply the recommended final torque to compress the washer and engage the retaining ring for a secure seal. After installation, pressurize the system and inspect the joint for leaks; if necessary, tighten to the recommended torque or disassemble and check component seating.

Usage recommendations

Use compatible tubing and fittings sized for 1/2" connections and follow system manufacturer torque specifications. Do not overtighten the nut to avoid deformation of the washer or damage to the tube. For long-term reliability, verify compatibility of materials with the system media and operating temperatures, and recheck joints after initial system pressurization.
