  • Loc-Line brand ensures consistent thread quality
  • Direct manufacturer shipment reduces handling delays

Valve pack for fluid control

The Loc-Line 39853 Female NPT Valve pack contains ten black valves designed for 1/2 inch NPT connections. They suit plumbing, coolant or air-line assemblies where manual on-off control is required. Each valve is new and supplied in a single package of ten units. This pack serves installers who need multiple identical shut-off points in one order.

Threaded connection constraints

The valves use a female 1/2 inch National Pipe Thread interface, so they only mate with matching male NPT fittings. Compatibility depends on the thread standard, not on hose barb or compression dimensions. Installers must verify that the mating components share the same thread form and nominal size before assembly. No other connection types are supported by this model.

Package quantity decides suitability

The pack quantity of 10 is the single figure that determines whether this product matches the project scope. A job requiring exactly ten valves can be fulfilled from one box; fewer or more valves mean opening multiple packs or leaving surplus units. Buyers who need a different count must source an alternative pack size.

Questions about this item

Should I choose the 10-piece pack or a different quantity?

The supplier offers this valve only in a 10-piece pack, so you receive ten units per order.

What does the 1/2-inch Female NPT connection mean when installed?

It mates with a 1/2-inch male NPT thread, creating a tapered seal that tightens as you turn it into a compatible fitting.

How does the NPT thread standard limit the fittings I can use?

NPT threads are tapered, so they seal only against matching NPT male threads; they will not seal on straight BSP or compression fittings.
