Jb Industries fp-b-168 Fusible Pipe Plug 1/4 Mpt 5 Pack

Product Description

The JB INDUSTRIES fp-b-168 is a 168-degree fusible pipe plug designed for use in refrigeration, HVAC, and related fluid systems. Sold in a five-pack, each plug features a 1/4 inch MPT (male pipe thread) connection and is machined from high-tensile brass consisting of 65% copper and 35% zinc. The fusible design allows the plug to melt and release pressure or fluid at the rated temperature threshold, providing a built-in safety function in pressurized systems. Long dryseal pipe threads minimize leakage and provide additional clearance for proper torque. JB Industries manufactures these fittings at their facility in Aurora, Illinois.

These fusible pipe plugs are suited for refrigeration service, HVAC equipment, marine applications, and hydraulic systems where a temperature-sensitive pressure-relief point is required. The brass construction provides compatibility with copper, brass, aluminum, steel, and plastic tubing where an acceptable connection can be formed. JB Industries brass fittings generally conform to SAE, ASA, and ARI standards, making them appropriate for professional refrigeration and ACR service applications. JB recommends applying compatible thread sealant and tightening 2-1/2 turns past hand tight during installation.

Key Features

• 168-degree fusible rating provides temperature-activated pressure release
• High-tensile brass alloy: 65% copper, 35% zinc for corrosion resistance and strength
• Forged construction maximizes strength and eliminates cracking risk
• Long dryseal pipe threads minimize leakage and ease assembly
• Rated to handle vacuum pressures up to 5,000 psi depending on size, materials, and conditions
• Made in the USA at JB Industries facility in Aurora, Illinois

Compatibility

Compatible with copper, brass, aluminum, steel, and plastic tubes where an acceptable connection can be formed. Conforms generally to SAE, ASA, and ARI standards for refrigeration, marine, and hydraulic service.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified refrigeration service professional. Isolate and depressurize the system before removing or installing any pipe plug. Apply a compatible thread sealant and tighten 2-1/2 turns past hand tight per JB Industries recommendations. Do not overtighten, as this may damage the dryseal threads or compromise the fusible element.
