Cps Products qcl14 Low Side Ac Coupler 1/4 Inch Sae

Product Description

The CPS PRODUCTS qcl14 is a manual low side coupler designed for use in R134a automotive and light-commercial air conditioning service work. It connects via a 1/4 inch SAE male fitting, providing a secure, leak-resistant link between the service manifold hose and the low side port of an A/C system. HVAC and automotive refrigeration technicians rely on this type of coupler during refrigerant recovery, evacuation, and recharge procedures. The manual design gives the technician direct control over refrigerant flow without the complexity of automatic valve mechanisms.

This coupler is suited for low side service port access on R134a systems, which are common in passenger vehicles and light-duty transport refrigeration. It is typically used during routine A/C service, including pressure diagnostics and refrigerant recharge. The 1/4 inch SAE male connection is a standard fitting size found on most manifold gauge hose sets used in mobile A/C service.

Key Features

• Manual low side coupler for direct technician-controlled refrigerant flow
• 1/4 inch SAE male connection for compatibility with standard manifold hose sets
• Designed for R134a refrigerant service applications
• Compact coupler form factor for access in tight engine bay spaces

Compatibility

Designed as an OEM-style service coupler for R134a low side service ports, compatible with standard 1/4 inch SAE male manifold gauge hose assemblies used in automotive and light-commercial A/C service.

Installation Notes

This coupler is installed by qualified HVAC or automotive refrigeration technicians familiar with refrigerant handling requirements under EPA Section 608 or Section 609 regulations, as applicable. Before connecting or disconnecting the coupler, ensure the system pressure is within a safe service range and use appropriate personal protective equipment to prevent refrigerant contact. Do not overtighten the fitting; hand-tighten and verify a secure seal before opening the valve. Always recover refrigerant before disconnecting from a charged system.
