Yellow Jacket 21112 Refrigerant Hose 12 Ft 45 Deg

Product Description

The YELLOW JACKET 21112 is a 12-foot refrigerant service hose from the Plus II line, designed for HVAC and refrigeration technicians performing system evacuation, charging, and pressure testing. The hose features a 45-degree Seal Right fitting, which reduces strain at the connection point and helps prevent refrigerant loss during connect and disconnect operations. Built for professional service work, it is constructed to withstand the pressures and chemical exposure common in refrigeration system service. HVAC technicians rely on this hose as part of a manifold gauge set for routine and diagnostic service calls.

This hose is suited for residential and light commercial HVAC and refrigeration service. It is sized at 12 feet, giving technicians enough reach to work comfortably around condensing units and evaporator coils without disconnecting and repositioning equipment. The 45-degree Seal Right fitting style is a standard configuration used across a wide range of manifold gauge sets and service ports.

Key Features

• 12-foot length provides working clearance around typical HVAC and refrigeration equipment
• 45-degree Seal Right fitting reduces hose stress at connection points and minimizes refrigerant loss
• Part of the YELLOW JACKET Plus II hose series, a recognized standard in professional refrigeration service
• Color-coded yellow, indicating use on the high-side or center manifold port depending on set configuration

Compatibility

Designed for use with standard refrigerant manifold gauge sets and service ports commonly found in residential and light commercial HVAC and refrigeration systems. Verify fitting thread size and port compatibility with your specific manifold gauge set before use.

Installation Notes

This hose is installed and serviced by licensed HVAC and refrigeration technicians. Before connecting or disconnecting refrigerant hoses, recover refrigerant per EPA Section 608 regulations and ensure system pressure is at a safe level. Hand-tighten fittings first, then snug with a wrench — do not overtighten, as this can damage the Seal Right fitting seat. Inspect hoses for cracks, kinks, or fitting wear before each use and replace if any damage is found.
