APEX DESIGN USA Banjo Fitting 1/4 NPT CRS to 3/8 in Braided Air Hose Adapter - Off-Road Air System

APEX Banjo Fitting for CRS to 3/8" Braided Air Hose

The APEX DESIGN USA Banjo Fitting is a small but important air-system adapter for connecting an APEX 3/8" braided air hose to a Compact Reel System with a 1/4 NPT CRS port. It is aimed at off-road, overland and performance vehicle builds where tyre inflation, deflation and onboard air accessories need the right connection hardware rather than a compromised universal fitting.

The key detail is the sealing method. This banjo fitting uses an O-ring seal against a flat or flush mounting surface, rather than sealing like a traditional 1/4 NPT thread. For buyers building or repairing an APEX air setup, that helps remove uncertainty around the hose-to-CRS connection and supports a cleaner, more dependable air-system layout.

What This Air Hose Adapter Does

This adapter joins two specific parts of the APEX air ecosystem: the APEX 3/8" braided air hose and the CRS 1/4 NPT port. It is not a complete compressor system, hose kit or tyre inflation tool. It is the connection point that lets the correct APEX hose interface with the Compact Reel System.

A mismatched air fitting can stop an otherwise well-planned system from sealing correctly. This banjo fitting solves that problem by using the specified connection sizes and an O-ring sealing arrangement designed around a flat/flush port surface.

Who This Banjo Fitting Is For

• APEX Compact Reel System users connecting an APEX 3/8" braided air hose.
• 4x4 and overland owners building a practical tyre inflation and deflation setup.
• Installers replacing or completing a CRS hose connection with the correct APEX fitting.
• Custom air-system builders who have confirmed a suitable flat/flush 1/4 NPT port surface.

This is selected by the air-system connection, not by vehicle model alone. If your Ford Raptor, touring 4x4 or workshop setup uses the correct APEX CRS and hose components, check the port and sealing surface before ordering.

Why Choose This Exact APEX Fitting

Choose this banjo fitting when the job is specifically to connect an APEX 3/8" braided air hose to a CRS 1/4 NPT port using an O-ring seal. If your system needs a different hose-end or quick-coupler connection, compare it with the APEX 3/8" braided hose to 1/4" NPT male fitting with cover nut or the APEX Compact Quick Coupler to 1/4 NPT adapter fitting.

For more control at the inflation point, the APEX Air Gauge ON/OFF Valve may also be useful. For multi-tyre layouts, the APEX 3/8" Free Flow Y fitting is a related APEX air-system component to consider.

Technical Specifications

Before Ordering

Check the connection at both ends of your air system before purchasing. You should confirm that you are using an APEX 3/8" braided air hose and that the CRS or receiving port has the required 1/4 NPT interface with a flat/flush surface for the O-ring to seal against.

If the port relies only on tapered thread sealing, this is not the right style of fitting. Clean, undamaged sealing faces are important for any O-ring connection, especially on air systems used away from workshop support.

Frequently Asked Questions

What does this APEX banjo fitting connect?

It connects an APEX 3/8" braided air hose to a 1/4 NPT CRS port on the APEX Compact Reel System.

Does it seal like a normal 1/4 NPT fitting?

No. The banjo fitting seals with an O-ring against a flat or flush mounting surface. It should not be treated as a traditional thread-sealed 1/4 NPT fitting.

Can it be used with systems other than the APEX CRS?

It may be suitable only where the receiving port has the correct 1/4 NPT connection and a flat/flush sealing surface for the O-ring. Check the port geometry before ordering.

Is this a full tyre inflation kit?

No. This is an individual banjo fitting / hose adapter. Hoses, couplers, valves, gauges and compressor components are separate unless shown as part of another product.

Is vehicle fitment confirmed?

This part is chosen by air-system compatibility rather than by a specific vehicle fitment. Confirm the APEX hose, CRS port and sealing surface on your setup.
