Ten white acetal shut-off valves with female NPT threads

Loc-Line

Loc-Line 39853 Flex Hose Valve Pack of 10

SKU CH-9WQD-6NPJ3

Pack of ten acetal shut-off valves with 1/2-inch female NPT threads for Loc-Line flex hose systems

  • Shut-off control for 1/2 in flex hose systems
  • Ten valves per pack for multiple installations
  • Acetal body resists corrosion and water damage
  • Female NPT threads connect to standard 1/2 in fittings
  • Compatible with acetone, alcohol, fuels, oils and solvents

Ten-piece valve pack

This Loc-Line 39853 pack supplies ten female NPT shutoff valves built from acetal. Each valve accepts a 1/2 in threaded connection and fits 1/2 in flex hose systems. The material resists corrosion and water, making the valves suitable for fluid-control tasks in workshops or maintenance bays. Buyers receive a ready-to-use quantity for multiple connection points.

Simple threaded installation

The valves install by threading the 1/2 in female NPT end onto a matching male fitting, so no specialised tools are required. Acetal construction keeps the parts light and reduces the risk of cross-threading compared with metal bodies. Compatible lubricants include acetone, alcohol, dish detergents, ethyl, gasoline, grease, lacquer solvents, oils and sodium hydroxide. Over-tightening can still strip the plastic threads, so hand-tighten plus a light turn is the practical limit.

Ten valves for parallel lines

With ten units in the pack you can equip several hose branches or keep spares on hand for quick replacements. Each valve handles the same 1/2 in hose diameter, so flow capacity is identical across every line. The shutoff function provides basic on-off control but does not regulate pressure or meter flow precisely. Systems that need proportional control or higher-pressure ratings will require a different valve type.

Questions about this item

How do I confirm the shut-off valve is sealing properly after threading it onto the 1/2 in NPT connection?

After installation, pressurize the line with a compatible fluid such as water or oil and inspect the female NPT joint for leaks; the acetal body is corrosion-resistant and water-resistant, so no seepage should appear at the threaded connection.

What comes in the package and do I need to buy the flex hose separately?

The pack includes ten female NPT shut-off valves made of acetal; the 1/2 in flex hose itself is not included and must be purchased separately to complete the assembly.

Which version of this valve pack should I choose for a 1/2 in Loc-Line system?

The 39853 pack is the only version listed and provides ten female NPT valves sized for 1/2 in flex hose systems, so it matches that requirement directly.
