Pack of ten acetal in-line check valves for 1/4-inch flex hose systems, corrosion- and water-resistant

  • Product typeDrain Components
  • Prevents back-flow with in-line check-valve design
  • Compatible with acetone, alcohol, detergents and solvents
  • Corrosion-resistant acetal material handles oils and chemicals
  • Ten valves per pack for multiple installations
  • Fits 1/4 in Loc-Line flex hose systems

Check Valve Pack for Flex Hose Systems

This pack contains ten in-line check valves built for 1/4 in Loc-Line flex hose assemblies. Each valve is moulded from acetal and rated for corrosion and water resistance. The non-threaded inline connection slips directly into compatible hose without tools. The valves tolerate a wide range of lubricants including oils, grease, gasoline, acetone, alcohols and sodium hydroxide solutions.

Suited for Fluid Control.

Maintenance teams and machine builders who need to prevent back-flow in coolant, lubricant or wash-down circuits will find these valves fit the existing 1/4 in hose system. They are not intended for high-pressure gas distribution, steam service or applications that require threaded or flanged connections. Buyers needing a different hose diameter or a threaded port should look at other valve types.

Ten Valves per Pack

The pack quantity of 10 is the decisive figure for planning spares kits or production line allocations. Each unit is the 29451 model and all share the same acetal construction and lubricant compatibility. Order multiples of this pack to match the required valve count.

Questions about this item

What hose size does the 1/4 in non-threaded connection on the 29451 check valve fit?

The valve is designed for 1/4 in flex hose systems, so the inline connection accepts 1/4 in inner-diameter hose without threads.

How do I orient the valve during installation so flow goes the right way?

Install the valve inline with the arrow on the body pointing in the direction of intended flow; reversing it will block the line.

When should I replace one of the acetal check valves in the pack of 10?

Replace a valve if it no longer prevents back-flow, shows cracking from chemical exposure, or the acetal body becomes brittle after prolonged use.
