Williams Comfort Products JHWRFW-28 Flare Nut Wrench Sae

Product Description

The WILLIAMS COMFORT PRODUCTS JHWRFW-28 is a flare nut wrench engineered for use on tube fittings, compression fittings, valves, and fasteners in SAE applications. Its high-carbon steel jaws snap open and then close around the fastener with six-point contact, which distributes load evenly and prevents distortion of thin-walled fittings. The unique ratcheting design requires only 30 degrees of rotation to advance, making it practical in confined spaces where a full swing is not possible. At 9.5 inches in length and 0.549 pounds, this wrench is light enough for overhead or awkward-angle work. HVAC techs, plumbers, and refrigeration mechanics who regularly work with flare and compression fittings will find this a reliable addition to their service kit.

This wrench is suited for both residential and light commercial service work wherever 6-point and 12-point tube fittings, compression fittings, or valve packing nuts must be tightened or loosened without rounding the fitting hex. Its 7/8 inch jaw opening targets the SAE fitting sizes commonly found on refrigerant lines, gas supply lines, and hydronic piping. The slim profile and snap-open jaw design allow access in tight panel spaces and behind equipment where standard open-end or box-end wrenches cannot reach.

Key Features

• Six-point jaw contact reduces the risk of rounding thin-walled fittings
• Snap-open jaw design allows the wrench to be placed around tubing and seated on the fitting hex without disconnecting the line
• 30-degree ratcheting rotation arc enables use in restricted-clearance locations
• High-carbon steel construction for durability under torque in field conditions
• Compatible with 6-point and 12-point tube fittings, compression fittings, and valves
• SAE sizing at 7/8 inch opening covers common refrigerant and gas line fitting sizes

Compatibility

Designed for use on 6-point and 12-point tube fittings, compression fittings, valves, and fasteners requiring a 7/8 inch SAE opening. Typical applications include refrigerant line fittings, gas supply connections, and hydronic system fittings across residential and light commercial systems.

Installation Notes

This wrench is used by licensed HVAC technicians, refrigeration mechanics, and plumbers during installation and service of tube and compression fittings. Always isolate the system — shut off refrigerant flow, gas supply, or water supply as applicable — before loosening or tightening fittings. Engage the jaw fully around the fitting hex before applying torque to avoid slippage. Follow applicable codes such as IFGC for gas line connections and manufacturer torque guidance for refrigerant fittings.
