Cd Valve cd2290r/2 Locking Cap 1/4 Inch A2L Pack of 2

Product Description

The CD VALVE cd2290r/2 is a 2-pack of red anodized aluminum locking caps designed for 1/4-inch Schrader valves used in A2L refrigerant systems. Each cap features an anodized aluminum exterior for corrosion resistance and a brass inner core for a precise, durable seal. The red color provides visual identification for A2L-designated service ports, helping technicians maintain refrigerant segregation and system integrity. These tamper-resistant caps are suited for residential HVAC maintenance and small-scale commercial installations where A2L refrigerant compliance and port security are required.

These locking caps are intended for use on 1/4-inch Schrader valve ports in A2L refrigerant systems. A2L refrigerants require dedicated, clearly marked service components to meet current industry safety and handling standards. The red anodized finish serves as a quick visual indicator at the service port. Licensed HVAC technicians working with A2L systems such as those using R-32, R-454B, or similar low-GWP refrigerants will find these caps appropriate for port security and leak prevention between service calls.

• Sold as a 2-pack for convenient service inventory

Compatibility

Designed for use with standard 1/4-inch Schrader valve service ports on A2L refrigerant systems.

Installation Notes

Installation is performed by a licensed HVAC technician in accordance with local codes and EPA Section 608 refrigerant handling requirements. Recover or isolate refrigerant as required before removing or replacing service port caps. Hand-tighten the locking cap onto the Schrader valve port until snug — do not over-torque, as aluminum threads can be damaged by excessive force. Confirm the cap seats fully to maintain a leak-free barrier between service intervals.
