  • In-line flow control for 1/2-inch systems

Loc-Line 39854-BLK In-Line Valve Pack

The Loc-Line 39854-BLK is a black in-line valve designed for fluid-control applications. It comes in a pack of ten so installers have multiple fittings ready for a single job. The valves suit maintenance technicians and DIY users who need reliable on-off control in compatible piping. Each unit is supplied new and ready for immediate installation.

Quarter-Turn Operation and Black Finish

The quarter-turn handle gives clear visual confirmation of open or closed state during routine checks. A black finish helps the valve blend with dark tubing or panel work in workshops and vehicle systems. Standard 1/2 inch connections allow direct insertion into matching lines without extra adapters. The pack quantity of ten supports projects that require several identical shut-off points.

Replaces Worn or Missing Shut-Off Valves

This pack replaces leaking, seized or missing in-line valves in existing 1/2 inch circuits. The jump is worth it when a system needs multiple reliable isolation points fitted at once. Buyers who need a different connection size or a higher-pressure rating should look elsewhere. The ten-piece bundle also avoids repeat orders for large installations.

Questions about this item

What is the valve size and how many come in the pack?

Each valve is a 1/2 inch in-line type and the pack contains 10 units.

What pipe diameter does the 1/2 inch valve fit?

The 1/2 inch size matches standard 1/2 inch Loc-Line hose and fittings for a direct push-fit connection.

How do you install the valve in the line and what is the common mistake?

Push the valve into the hose ends until seated; the common mistake is not pushing both sides fully home, which can cause leaks.
