APEX DESIGN USA Air Gauge ON/OFF Valve for Inflation Control
The APEX DESIGN USA Air Gauge ON/OFF Valve is an inline control valve for compatible APEX air inflation systems. It is for off-road, overlanding and workshop users who want a simple manual shut-off point in a quadAIR, single, dual or multi-port tyre air setup using 3/8 braided air line.
As an air system becomes more than a basic compressor hose, control matters. An inline ON/OFF valve helps you start or stop air flow at a chosen point, making tyre pressure routines easier to manage and helping keep a modular air setup organised around the vehicle.
What This Air System Valve Does
This is not a compressor, gauge or complete inflation kit. It is the manual control point that sits within an existing APEX DESIGN USA air management layout and turns flow on or off. Choose it when you need a dedicated shut-off valve rather than another hose adapter, quick coupler or reel.
Adds manual air flow control to a compatible APEX DESIGN USA inflation system
Suited to quadAIR, single and dual inflation system layouts
Intended for use with 3/8 braided air line
Useful for modular tyre inflation and deflation workflows
Helps create a cleaner, more controllable air system for off-road and overland use
Who This Inflation Valve Is For
This valve suits owners already building around APEX DESIGN USA air components, especially vehicles used for regular tyre pressure changes on road, trail and overland trips. It is also a useful spare or additional shut-off point for a custom air setup where the hose route, air gauge position or control location needs more precise management.
Can be used as an inline ON/OFF valve for single, dual and quadAIR inflation systems.
Intended for use with 3/8 braided air line.
Check your air line and fitting requirements before ordering, rather than relying on a vehicle model tag alone.
APEX DESIGN USA references a Male 3/8 Swivel to Male 3/8 Hose Barb fitting, SKU X02-11-007, as a compatible fitting where required.

Questions before you order
Frequently asked questions
Is this a complete tyre inflation system?
No. This is an inline ON/OFF valve used within a compatible air system. It does not replace a compressor, hose reel, gauge assembly or the required fittings for your layout.
Which air systems is it intended for?
It is intended for APEX DESIGN USA quadAIR systems and can be used as an inline valve for single, dual and quadAIR inflation system layouts.
What air line does it work with?
The stated line compatibility is 3/8 braided air line. Check your existing hose size and fitting type before ordering.
Does vehicle fitment matter?
This part is best selected by air system compatibility and hose specification rather than by vehicle model alone. If your Ford Raptor, overland build or workshop setup uses compatible APEX air components, check the line and fitting requirements before fitting.
Are fittings included?
No included accessories are explicitly listed. APEX DESIGN USA references a compatible Male 3/8 Swivel to Male 3/8 Hose Barb fitting, SKU X02-11-007, for installations that require it.
When should I add an extra ON/OFF valve?
Add one when you want an extra manual shut-off point, a more controlled air gauge location or better separation between sections of a modular tyre inflation system.
