Loc-Line 49425 Connector 1.04 in 170°F 50PK

Product identity

The Loc-Line 49425 is a drain connector supplied in a pack of fifty pieces. It is intended for plumbing professionals and maintenance teams who need a reliable non-threaded to male NPT transition in fluid-handling systems. The component suits workshops and industrial sites where chemical compatibility and pressure tolerance are required. Buyers who need a threaded connection at both ends or a larger bore size will not find this model suitable.

Interface limits

The connector carries a maximum pressure rating of 110 psi and is rated for continuous service up to 170 degrees Fahrenheit. End one is a non-threaded quarter-inch diameter while end two provides a male NPT thread of one-eighth inch. The housing resists a broad range of lubricants and chemicals including acetone, alcohol, dish detergents, ethyl compounds, gasoline, grease, lacquer solvents, oils and sodium hydroxide. Systems operating above the stated pressure or temperature limits must use a different fitting.

Installation notes

Installation is a simple push-on to the quarter-inch tube followed by threading the NPT end into the mating port. The pack quantity of fifty supports high-volume jobs without reordering. A common issue arises when the tube is not cut squarely or fully seated, creating a leak path at the non-threaded end. Over-tightening the NPT thread can strip the softer port material, so hand-tight plus one turn is the usual practice. Ensure the fluid media is listed in the chemical compatibility guide before assembly.
