Product Identity

The Loc-Line 41411 is a pack of four flex hose adapters that connect a 1/4 inch non-threaded end to an 1/8 inch female NPT threaded end. They suit technicians and hobbyists routing coolant, lubricant or air lines in tight machine spaces.

Compatibility Check

Verify that your existing hose has a 1/4 inch non-threaded opening and that the receiving port accepts an 1/8 inch female NPT thread. The adapters handle up to 110 psi and resist acetone, alcohol, gasoline, oils, sodium hydroxide and listed solvents.

Upgrade Context

These adapters replace makeshift fittings or mismatched reducers that leak under pressure or degrade in chemical contact. The four-pack makes sense when you are plumbing multiple junctions or want spares for future maintenance on the same system.

Questions about this item

What comes in the pack and is anything else needed to connect 1/4 in hose to a 1/8 NPT port?

The pack contains four 1/4 in to 1/8 in NPT female socket adapters. Each has a non-threaded 1/4 in end for push-on hose and a 1/8 in female NPT thread. No extra parts are required if your hose fits 1/4 in and the port is 1/8 NPT.

Should I choose this 41411 adapter or a different size for my 1/4 in hose and 1/8 NPT female thread?

Model 41411 is built for exactly that combination: a 1/4 in non-threaded hose end and a 1/8 in female NPT thread. If either the hose diameter or the port thread differs, a different adapter would be needed.

The spec lists 110 psi maximum pressure — what does that mean when the adapter is installed on a pressurised line?

The 110 psi rating is the highest pressure the adapter can safely withstand when properly seated. Operating above that pressure risks leaks or failure, so the system pressure must stay at or below 110 psi.
