Supco supco-sfl1450 Plastic Locking Cap 0.25 in 50 Pack

Product Description

The SUPCO supco-sfl1450 is a plastic safety locking cap designed to seal and secure 0.25-inch refrigerant service ports. These caps provide a tamper-resistant closure on Schrader valve ports, helping prevent refrigerant loss, moisture ingress, and debris contamination. Sold in a 50-pack, they are a standard consumable for HVAC technicians performing system service, leak checks, or seasonal maintenance. Each cap snaps into place and locks to reduce the chance of accidental or unauthorized removal.

These locking caps are used on residential and light commercial HVAC systems wherever 0.25-inch service ports are present. Common install scenarios include capping high-side and low-side service valves after refrigerant recovery, recharge, or pressure testing. The 50-pack quantity is suited for service vehicles, shop stock, or multi-unit service calls where caps are routinely replaced as a best practice.

Installation Notes

Installation is performed by licensed HVAC technicians as part of standard service port maintenance. Always recover or isolate refrigerant pressure before removing an existing cap and servicing the port. Ensure the port valve core is fully seated before threading on the replacement locking cap. Hand-tighten only; do not use tools that could crack or deform the plastic cap body.
