R410 RED 5/16in 2PK

The DiversiTech® RSC-RED-02-E refrigerant locking caps by Sentry™ are a quick and easy way to comply with the IRC and IMC code requirement that all outdoor access ports on A/C and refrigerant equipment be tamper resistant. This cap is anodized in red color for easy identification of R-410 refrigerant and is designed for 5/16 in. access ports typically used on mini-splits and European styles of A/C systems. An O-ring seal is also pre-installed to prevent leaks.
