APEX DESIGN USA 3/8" Free Flow Y Fitting - Multi-Tyre Inflation Adapter

APEX 3/8" Free Flow Y Fitting for Multi-Tyre Inflation

The APEX DESIGN USA 3/8" Free Flow Y Fitting is a compact air-line splitter for APEX 3/8" braided air line systems. It is made for drivers building a practical off-road or overland inflation setup, allowing one hose to split into two feeds for multi-tyre inflation.

Airing tyres one at a time can slow you down after a trail, beach run or loaded touring section. This Y fitting helps reduce the time spent managing pressures by letting a compatible Apex air line feed two tyre inflation points from a single line, provided the rest of the air system is set up for that use.

What This Free Flow Y Fitting Does

• Splits one Apex 3/8" braided air hose into two feeds.
• Supports multi-tyre inflation setups for off-road and expedition vehicles.
• Helps create a cleaner, more flexible air-line layout.
• Useful when building or expanding an APEX DESIGN USA air system.
• Compact supporting fitting rather than a complete inflation kit.

Who This Air System Adapter Is For

This fitting is for owners already using, or planning to use, Apex 3/8" braided air line. It suits overlanding, touring and 4x4 builds where quick tyre pressure changes are part of the routine.

Although Ford Raptor is a common search context for onboard and portable air systems, this part is not confirmed as a vehicle-specific Ford Raptor fitting. The key compatibility point is the air line: it is confirmed for Apex 3/8" braided air line.

Compatibility Notes for APEX 3/8" Braided Air Lines

The buyer decision is simple: choose this part when you need a one-into-two splitter for an Apex 3/8" braided hose setup. If your system uses different hose sizes, different fittings or non-Apex air line, check compatibility before ordering.

For related line connections, the APEX DESIGN USA 3/8" Braided Hose to 1/4" NPT Male Fitting may help complete a compatible air system layout.

Technical Specifications

Building the Rest of the Inflation Setup

A Y fitting works best as part of a planned air system. If you are building around a portable hose layout, the APEX DESIGN USA Compact Reel System is a relevant companion product. For control at the inflation point, consider the APEX DESIGN USA Air Gauge ON/OFF Valve.

If your setup needs quick hose connection, the APEX DESIGN USA Compact Quick Coupler to Apex Nylon Braided Hose is another useful Apex air-system component to compare before finalising your layout.

Before Ordering

• Confirm your hose is Apex 3/8" braided air line.
• Check the rest of your compressor, gauge, valve and coupler layout.
• Remember this is a fitting only, not a complete compressor or four-tyre inflation kit.
• Use suitable installation practice for your air system and check connections before use.
