Who Is This For?
Whether you're a certified HVAC technician, a home improvement enthusiast, or someone maintaining your own mini-split or central air system, this adapter bridges the gap between your vacuum pump's 1/4" SAE port and the standard 5/16" SAE quick-connect fittings found on R410a manifold sets. It's a small part that makes a big difference in getting the job done right.

Frequently Asked Questions
Q: What does this brass R410a vacuum pump adapter do?
A: This adapter converts a 5/16" SAE female quick coupler to a 1/4" SAE male fitting. It allows you to connect a standard vacuum pump (which typically uses a 1/4" SAE port) to R410a manifold gauge sets or service hoses that feature 5/16" SAE quick-connect fittings — making it an essential tool for air conditioning evacuation and charging procedures.
Q: Is this adapter compatible with refrigerants other than R410a?
A: Yes. While it is designed with R410a service work in mind, the 5/16" SAE to 1/4" SAE fitting size is also compatible with other common refrigerant systems that use the same SAE port standards. Always verify your equipment's fitting requirements before use.
Q: What material is this adapter made from, and why does it matter?
A: The adapter is machined from an aluminium-copper (brass) alloy. Brass is widely preferred for refrigerant fittings because it offers excellent resistance to corrosion, handles the pressures involved in HVAC service work, and provides a reliable, leak-free seal when properly torqued — ensuring safe and efficient operation.
Q: How many adapters are included in the package?
A: The package includes 2 brass adapters, so you have a spare on hand or can set up two service lines simultaneously.
