D.O.T. 3/8" AIR LINE x 3/8" AIR LINE, BULKHEAD UNION USED WHEN RUNNING AIRLINE THROUGH FIREWALL, FRAME, METAL, ETC...
PLEASE READ BEFORE PURCHASING:Due to the sensitive nature of the construction of the fittings, our manufacture does not give us a warranty. This is due to the history of many end user errors, such as (1)not cutting the air line with the proper sharp cutting tool, (2)not wiping off debris from the air line before insertion, (3)not deburring hard line before insertion. Any of these "bad" practices will result in "nicking" the internal O-ring and or contaminate the seal, either way, resulting in a leak. Because of this, we cannot offer any warranty, so there is absolutely NO RETURNS ON PTC FITTINGS for ANY reason. But rest assured, if you practice the proper cutting, cleaning and deburring techniques that are necessary, you should not have ANY problems with our fittings. We use these same fittings daily on our installations and our personal vehicles.
