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.
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.

It is used to split one Apex 3/8" braided air hose into two feeds, making it useful for multi-tyre inflation setups.
Does it fit all air hoses?
No. Confirmed compatibility is with Apex 3/8" braided air line. Other hose sizes or brands should be checked before ordering.
Is this a complete tyre inflation system?
No. This is a supporting Y fitting. You will still need the correct air line, compressor source, couplers, gauge or valves for your chosen setup.

It can be considered for a Ford Raptor air-system build only if the build uses compatible Apex 3/8" braided air line. No vehicle-specific fitment is confirmed.
Are pressure, material or temperature ratings provided?
Those specifications are not currently confirmed, so check your full air system requirements before use in demanding applications.
