Make regular hoses easier to connect and disconnect.
The Uniweld EZ-Turn Anti-Blowback Adaptor range is built for technicians who want better control at the service port without replacing their whole hose set. The adaptors fit between the hose and access fitting to help reduce spray-back and make repeated hose connection work easier by hand.
- Converts regular service hoses into EZ-Turn anti-blowback hose connections.
- Helps reduce refrigerant spray-back during disconnection.
- Supports cleaner, more controlled hose connection practices.
- Available in straight and 90 degree layouts for different access positions.
- Includes standard 1/4 in options and 5/16 in service-port options.
- Useful for charging, recovery, evacuation and diagnostic service work.
What it helps with
Use the EZ-Turn adaptor range when a hose setup needs better control at the service port, especially around tight cabinets, awkward access angles or systems where clean disconnection matters.
- Connecting standard hoses to access fittings with easier fingertip control.
- Reducing refrigerant loss and spray-back when disconnecting service hoses.
- Choosing a straight or 90 degree path based on available clearance.
Adaptor selector
Choose by port size and access angle.
Select the adaptor that matches the service-port connection and the space available around the equipment cabinet.
UW-EZAB
1/4 in M.F. × 1/4 in F.F.Use where a straight service hose connection has enough clearance from the panel, cabinet or nearby pipework.
UW-EZAB90
1/4 in M.F. × 1/4 in F.F.Use where the hose needs to leave the service port at a right angle to reduce bend stress or improve access.
UW-EZABM
1/4 in M.F. × 5/16 in F.F.Use for compatible 5/16 in service-port work when a straight connection is the cleanest route.
UW-EZABM90
1/4 in M.F. × 5/16 in F.F.Use for compatible 5/16 in service-port work where cabinet depth or port position calls for a right-angle connection.
Connection check
Match the adaptor before the hose goes on.
The correct adaptor depends on the service-port size, connection angle and the direction the hose needs to run once connected. Confirm the fitting style before pressurising, charging or disconnecting from the system.
Check whether the job needs a standard 1/4 in connection or a 5/16 in service-port option.
Use straight adaptors for open access and 90 degree adaptors where the hose needs to turn quickly out of the port.
Check threads, seals and hose condition, then follow normal HVAC/R refrigerant handling procedures.
