The Sentry Locking Caps full line of refrigerant locking safety caps work with access ports on any HVAC system and refrigeration equipment.

Each locking cap is color-coded for easy identification and to prevent accidental mixing of refrigerant gases. Featuring an anodized aluminum casing and a threaded brass insert, the caps are tamper resistant and can withstand the harshest weather. 

The line helps contractors meet new state and local safety requirements for outdoor HVAC/R access ports.

For systems with R-410 refrigerant, contractors can choose two Red locking cap models in either a ¼ inch or a 5/16 inch size. For systems with R-22 refrigerant, a Green ¼ inch cap is available. The complete line also contains a Universal Silver locking cap in a ¼ inch size that can be used on a variety of service ports. Each model can be purchased in either a 4-10- or 50-piece pack. The Universal cap is also available in a 500-piece pack.
