What to Compare Before Buying
- Thread standard: Match the fitting to 1/8 NPT, 1/8 BSPP or M10x1 only where the connection point uses the same thread.
- Connector style: Check that an 8 mm female quick disconnect fits the hose or adapter you already have.
- Pack quantity: This set contains 3 pieces, so compare that with how many connections you need to make.
- Pressure requirement: The stated 3000-5000 psi rating should suit the system you plan to connect.
- Included washer: Confirm whether you need a sealing ring washer in the fitment you are replacing.
What Else You May Need
A compatible high-pressure hose, tank or fill setup with the matching thread and connector type is needed for use. Check the exact connection standard before ordering.
Before You Decide
Confirm the thread standard, the 8 mm quick disconnect connection and the 3-piece pack quantity before choosing. The pressure rating and included sealing ring washer are also important if you are replacing an existing fill fitting or building a matching setup.
