Connect your tyres, open the slide valve and manage the pressure from one gauge. The APEX Air-Eco four-tyre kit saves you moving an inflator from wheel to wheel and lets the connected tyres equalise together. Its cut-to-fit hose makes the installation suit your vehicle rather than leaving you to deal with a generic tangle.
SKU: X02-17-042-3
The kit supplies 42 ft of APEX braided air line, enough for vehicles up to a 150 in wheelbase. Measure your routes and cut the sections during assembly, leaving the movement and access space the guide requires. The hose is 3/8 in outside diameter with a 1/4 in bore; 3/8 in is not the internal diameter.
Push the sleeve down to inflate and lift it to stop airflow and read pressure. For deflation, disconnect the air source and open the valve, then close it to stop or read the pressure. The included 90 psi composite inflator gives you one place to control the connected tyres without holding a trigger.
Connected tyres equalise. When your vehicle requires different front and rear road pressures, manage the appropriate tyres separately to reach those settings. Total filling time still depends on the compressor, tyre volumes and starting pressures; a four-hose kit does not multiply the compressor's airflow.
Our ARB CKMTA12 brushed twin and CKBLTA12 brushless twin are useful on-board compressor options for repeated tyre inflation. Match the kit's included 1/4 NPT adapter to the compressor's outlet connection and follow its heat-rated hose requirements. The compressor and any outlet coupler are separate purchases.
The APEX Air-Eco system case gives the hose assembly a tidy place to live, and the composite universal gauge snap mount is the mount shown for this inflator. The older X02-08-003 PPG mount is not compatible. The case and optional mount are separate.
If a hose end is damaged, the threaded hose fittings let you trim or repair a section following the instructions. The APEX braided-line splice is useful when repairing or adding a section of the matching air line.

You assemble it to suit your vehicle, measuring and cutting the supplied hose before fitting the junctions and chucks. That is what keeps the finished hose lengths appropriate to your wheelbase.
Yes. The kit includes a 90 psi APEX composite inflator, four closed-flow chucks, three composite Y-fittings and 42 ft of hose.
No. It makes connecting, equalising and controlling several tyres more convenient. The compressor's output and the amount of air your tyres need still determine the filling time.
Use closed-flow chucks for this multi-tyre arrangement. They stop air escaping through a disconnected branch. Four suitable closed-flow chucks are included.
The tyres connected together equalise. Work with the required tyres separately when you need different final pressures, following your vehicle's road-pressure requirements.
The system case is a separate accessory. It is a useful addition for keeping the assembled hoses together between trips.
