Yellow Jacket 93394 Flare Cap and Strap 1/4 Inches

Product Description

The YELLOW JACKET 93394 is a flare cap and strap assembly designed to seal and protect 1/4-inch flare fittings on refrigerant lines and HVAC service ports. The cap threads onto the flare fitting to prevent contamination, moisture ingress, and refrigerant loss when the system is not under active service. The attached strap keeps the cap tethered to the fitting, reducing the chance of losing the cap during service calls. HVAC technicians and refrigeration service pros typically install this hardware during system commissioning, leak isolation, or routine maintenance.

This flare cap and strap is suited for use on residential and light commercial HVAC and refrigeration equipment anywhere a 1/4-inch flare service port or refrigerant line connection needs to be capped between service intervals. It is a standard accessory for field technicians who work with flare-type refrigerant fittings and need reliable port protection without tools or additional hardware.

Key Features

• Fits 1/4-inch flare fittings for a secure, leak-resistant seal
• Integrated strap keeps cap retained at the fitting to prevent loss during service
• Protects flare port from moisture, debris, and contamination

Compatibility

Designed for use with standard 1/4-inch flare fittings commonly found on residential and light commercial HVAC and refrigeration systems.

Installation Notes

Installation and removal of flare caps should be performed by a licensed HVAC or refrigeration technician. Before removing or installing caps on refrigerant circuits, recover system refrigerant per EPA Section 608 requirements and ensure the circuit is depressurized as appropriate for the task. Thread the cap onto the flare fitting by hand until snug — do not overtighten, as flare fittings can be damaged by excessive torque.
