Loc-Line 49431 Socket for 1/8 FNPT

The Loc-Line 49431 is a pack of twenty sockets designed to connect 1/4 inch non-threaded ends to 1/8 inch female NPT threads. It serves plumbers, maintenance technicians and industrial assemblers who need a quick, pressure-rated connection for fluid or air lines. Each socket is rated for a maximum pressure of 110 psi.

Sustained-pressure performance

Under continuous load the socket holds its 110 psi rating without creep or leakage. The material resists a wide range of lubricants and chemicals including acetone, alcohol, dish detergents, ethyl compounds, gasoline, grease, lacquer solvents, oils and sodium hydroxide. This compatibility ensures the joint remains intact during prolonged exposure to aggressive media.

Installation notes and common pitfalls

Installation is a simple push-fit onto the 1/4 inch tube followed by threading the 1/8 NPT end into the mating port. The most frequent issue is cross-threading the fine NPT threads or over-tightening, which can strip the female port. Ensuring the tube is cut square and fully seated before tightening prevents leaks at the non-threaded end.

Questions about this item

Will the Loc-Line 49431 socket handle continuous 110 psi pressure without leaking?

The socket is rated for a maximum pressure of 110 psi, so it is designed to hold that pressure continuously when installed correctly with compatible sealant on the 1/8 inch FNPT threads.

What pipe thread sealant or tape do I need for the 1/8 FNPT connection?

The manufacturer lists compatible lubricants including acetone, alcohol, dish detergents, ethyl, gasoline, grease, lacquer solvents, oils and sodium hydroxide, so standard PTFE tape or pipe dope suitable for those chemicals can be used.

Can I connect this 1/4 inch non-threaded socket to my existing 1/4 inch Loc-Line hose segments?

Yes, the End 1 non-threaded diameter is 1/4 inch, which matches standard Loc-Line 1/4 inch modular hose segments for a push-fit connection.
