Jb Industries a31520 Swivel Cross with Depressor

Product Description

The JB INDUSTRIES a31520 is a swivel cross fitting with a built-in depressor, designed for use on refrigerant access ports in HVAC and refrigeration systems. The 1/4 inch female SAE swivel nut connection allows the fitting to rotate freely, reducing hose torque and making multi-port access setups easier to manage in tight equipment spaces. The integrated depressor engages the Schrader valve core automatically when the fitting is attached, allowing refrigerant or vacuum to flow without a separate valve core tool. This fitting is installed by licensed HVAC and refrigeration technicians during system service, evacuation, and charging procedures.

The a31520 is suited for residential and light commercial HVAC service work where technicians need simultaneous access to multiple ports on a refrigerant circuit. The cross configuration provides four ports in a single compact body, supporting manifold gauge set connections, vacuum pump lines, or refrigerant charging equipment at the same service point. It is commonly used during system diagnostics, evacuation, and refrigerant recovery or recharge operations on split systems, packaged units, and refrigeration equipment.

Key Features

• Swivel cross body provides four-way port access from a single connection point
• Integrated depressor engages Schrader valve cores automatically on attachment
• 1/4 inch female SAE swivel nut rotates freely to reduce hose and manifold torque
• Compact design suited for confined equipment compartments
• Supports simultaneous use of multiple service hoses or gauges

Compatibility

Designed as an OEM-style service fitting compatible with standard 1/4 inch SAE female refrigerant access port applications on HVAC and refrigeration equipment.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician in accordance with applicable EPA Section 608 regulations and local codes. Recover or isolate refrigerant pressure before attaching or removing access fittings to prevent uncontrolled refrigerant release. Hand-tighten the swivel nut fully before opening any service valves, and inspect the fitting and O-rings for damage prior to use. Do not over-torque the swivel nut connection, as this can damage internal seals or valve core threads.
