SKU CH-PXHH-1FFK6 MPN 51805

Half-inch NPT male connector joins Loc-Line hose sections up to 60 psi in packs of four

  • TypeDrain Components
  • Secure connections up to 60 psi rating
  • Four connectors included for multiple installations
  • Compatible with acetone alcohol detergents and solvents
  • NPT male thread ensures standard plumbing fit
  • Ready for gasoline oil and chemical exposure

1/2-inch NPT connector pack

This pack contains four Loc-Line 51805 connectors built for 1/2-inch NPT male threads on one end and a non-threaded 1/2-inch bore on the other. The fittings are rated to a maximum pressure of 60 psi and resist a wide range of lubricants including oils, solvents and sodium hydroxide. They suit fluid-handling systems that need a quick, tool-free connection point.

Suits low-pressure fluid lines only

Installers running water, air or compatible chemical lines at or below 60 psi will find these connectors a direct fit. Systems that operate above 60 psi, require threaded ends on both sides or need a different thread standard should look at alternative fittings. The single male NPT end also means they cannot join two female ports without an additional adapter.

60 psi maximum pressure rating

The 60 psi limit is the decisive figure when selecting this part. Any circuit that may see pressure spikes above that value needs a higher-rated connector regardless of thread size or chemical compatibility.

Highlights

  • Secure connections up to 60 psi rating

Questions about this item

What size NPT male thread does the Loc-Line 51805 connector provide for connecting to existing piping?

The connector ends in a 1/2 inch NPT male thread so it can screw directly into a matching female fitting on your current pipework.

Will the connector handle the pressure in a typical low-pressure coolant or air line without leaking?

It is rated to a maximum of 60 psi which covers most low-pressure coolant and compressed-air circuits found in workshop equipment.

How can I confirm the joint is sound after I thread the connector into place?

Pressurise the system up to its normal working pressure and check the threaded joint for any sign of seepage; a dry joint at operating pressure means the seal is holding.
