GRACO OEM PIPE COUPLING FOR RELIABLE HARDLINE PLUMBING
Graco hardline coupling for joining 1/4 inch and 3/8 inch pipe sections in diesel or lube oil systems. OEM part for reliable plumbing.
Simple diameter step
Joins 1/4 inch to 3/8 inch hardline pipe without custom machining or bulky adapters. Graco OEM part means known tolerances and seal surfaces. Weighs 70 grams, so it does not load pipe runs or need extra support brackets in typical installations.
Diesel, lube, air
Used in diesel transfer hardline runs, lube oil dispensing systems, and compressed air plumbing. Compact design fits tight spaces in pump assemblies or under benches. Standard Graco part number makes reordering straightforward when you expand the system or stock spares.
