Product Description
The DIVERSITECH dn5-4 is a 1/4-inch brass hex valve cap designed to seal service ports on HVAC refrigerant lines and valves. Built for durability, it resists mechanical shock and vibration, making it a reliable choice for protecting Schrader valves and service ports from contamination and accidental refrigerant loss. The cap's hex profile allows for tool-assisted tightening, ensuring a secure, leak-resistant seal. Licensed HVAC technicians typically keep these caps on hand as standard service components during system installation, maintenance, and repair work on ducted systems.
This valve cap is suited for use on ducted HVAC systems where 1/4-inch service port protection is required. It is commonly installed on refrigerant line service valves, Schrader valve cores, and similar fittings during routine maintenance or after refrigerant system service. The brass construction provides corrosion resistance and long-term reliability in both indoor and outdoor installation environments.
Key Features

Installation Notes
Installation is performed by licensed HVAC technicians during system service or refrigerant handling procedures. Always recover or isolate refrigerant and depressurize the service port before removing or replacing valve caps. Use an appropriately sized hex wrench or nut driver to seat the cap fully without overtightening. Follow all applicable EPA Section 608 refrigerant handling regulations during service.
