1/4” Thru-Bulk Bulkhead Plastic Hose Barb Fittings Union Adapter Fittings for Aquarium Fuel Gas Liquid Air with Metal washers (Pack of 6)

Parts worked just as they should. My project turned out great.

Exactly what I ordered

These pieces worked perfect.

Works well for this. Put on container lid and the. Connect hose to pump on the outer side and hose inside container. Airtight works well.

Purchased items in conjunction with Power Steering Fluid replacement. Set tubes into container to capture expelled P/S fluid. Fitting perfectly fit P/S fluid line from car to create a sealed system.
