Straight Airline Connectors

Always a smooth transaction!

I had to trim an inch of air line to get a tight fit but that's only because my other air connection was a bit oversized and stretched out the air tube. These do the job at a much lower price than you'll find them for locally.

These are simple , but work great to connect tubing

These are exactly what they say, not fancy but gets the job done, have purchased dozens of these from Co-op and never had a defect or failure.

Work very well. Drill a 3/16 hole into the pvc pipe.
then attach the valve to the drill bit, use the drill, and it will thread it into the pvc pipe
