  • Product typeDrain Components
  • Directs flow precisely with 0.5 in hole diameter

Round nozzle pack for coolant systems

This pack contains four Loc-Line 51803 round nozzles designed for 1/2 inch non-threaded connections. Each nozzle directs fluid flow in machining or coolant applications. The acetal construction resists a wide range of shop chemicals. They connect directly to compatible Loc-Line hose segments.

Suited for standard 1/2 inch Loc-Line assemblies

These nozzles fit existing 1/2 inch Loc-Line systems where a fixed round outlet is needed. They are not for threaded pipe connections or high-pressure hydraulic lines above 60 psi. Builders needing adjustable flow angles or threaded fittings should look at other component types.

56 degree maximum swing articulation

The nozzle pivots up to 56 degrees from centre to aim coolant precisely at the work zone. This range sets the positioning flexibility for each outlet. It operates within a 170 degree Fahrenheit temperature limit and 60 psi pressure rating.

Questions about this item

How can I confirm the Loc-Line 51803 round nozzle is working correctly after installation?

Check that coolant flows evenly through the 0.5 in hole diameter at up to 60 psi and that the arm swings smoothly within the 56 degree maximum angle without leaks at the non-threaded 1/2 in connection.

What comes in the package and what additional parts are needed to use the Loc-Line 51803 nozzles?

The pack includes four round nozzles with 1/2 in non-threaded connections; you will need compatible Loc-Line hose segments and any required fittings to complete the coolant delivery assembly.

Which version of the Loc-Line 51803 should I choose for my setup?

The 51803 is a single specification — round nozzle, 1/2 in connection, 0.5 in hole, 56 degree swing, 60 psi and 170 °F ratings — so select it when those exact parameters match your machine's coolant requirements.
