Yellow Jacket 40331 Red Pressure Gauge Quick Connect

Product Description

The YELLOW JACKET 40331 is a red pressure gauge fitted with a quick-connect fitting, designed for use in refrigeration and HVAC service work. The red color coding follows standard manifold gauge conventions for the high-side circuit, helping technicians quickly identify the correct gauge during service calls. Quick-connect fittings allow fast, tool-free attachment and detachment from service ports, reducing the risk of refrigerant loss during connection changes. This gauge is a component-level replacement or addition suited for HVAC and refrigeration service technicians working on residential and light commercial equipment.

The 40331 is intended for use in HVAC and refrigeration service applications where a red high-side pressure gauge with quick-connect compatibility is required. It is typically used by licensed HVAC technicians during refrigerant system diagnostics, charging, and recovery procedures. The quick-connect design is compatible with YELLOW JACKET manifold gauge sets and service hose assemblies that accept this fitting standard.

Key Features

• Red color coding identifies this as a high-side gauge per standard manifold conventions
• Quick-connect fitting allows fast attachment and detachment without additional tools
• Designed for refrigeration and HVAC refrigerant circuit service applications
• Component-level replacement for worn or damaged gauges in existing manifold sets

Compatibility

Designed as a replacement or add-on red pressure gauge for YELLOW JACKET manifold gauge sets and service assemblies that use compatible quick-connect fittings. Refer to your existing manifold set documentation to confirm quick-connect fitting compatibility before installation.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician familiar with refrigerant handling requirements under EPA Section 608. Recover system refrigerant and relieve pressure from the service hose before disconnecting or replacing any gauge. Inspect the quick-connect o-ring and seating surface for wear or damage before placing the gauge into service. Handle the gauge face carefully to avoid impact damage that can affect calibration accuracy.
