The kit pairs the APEX 90 PSI inflator and its slide-valve control with four closed-flow push-on chucks, three composite Y-fittings and 42 feet of 3\/8 inch nylon braided air line that you cut to your own wheelbase during assembly, so nothing drags in the mud or catches a tyre. Push the sleeve down to inflate; pull up to stop and read pressure.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDrivers airing four tyres at every trailhead who are done doing it one corner at a time\u003c\/li\u003e\n\u003cli\u003eGroup runs and events where pit-stop speed matters\u003c\/li\u003e\n\u003cli\u003eSetups wanting equal pressures across the axle set without chasing each wheel with a gauge\u003c\/li\u003e\n\u003cli\u003eVehicles up to a 150 inch wheelbase - the supplied line is cut to fit yours exactly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eOne Source, Four Corners\u003c\/h2\u003e\u003cp\u003eBecause all four tyres share one line, the system self-balances: air flows until the set equalises, which is the fastest route to matched pressures side to side. Compared with single-tyre airing - four hook-ups, four gauge checks, four chances to mismatch - the multi-line approach turns pressure changes into one supervised job. It connects to any compressor via the included 1\/4 inch NPT adapter and works with standard Schrader valves, so no valve conversion is needed first.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: APEX Design USA\u003c\/li\u003e\n\u003cli\u003eProduct Type: Four-tyre inflation and deflation kit\u003c\/li\u003e\n\u003cli\u003eSKU: X02-17-042-3\u003c\/li\u003e\n\u003cli\u003eIncluded Items: APEX 90 PSI inflator (slide valve), 4 closed-flow push-on chucks, 3 composite Y-fittings, 42 ft of 3\/8 in nylon braided air line, 1\/4 in NPT compressor adapter\u003c\/li\u003e\n\u003cli\u003eValve Compatibility: Standard Schrader valves\u003c\/li\u003e\n\u003cli\u003eWheelbase Coverage: Up to 150 inches (lines cut to length during assembly)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cp\u003eAssembly is part of the product: measure your wheelbase, cut the braided line to suit, and build a harness that fits your vehicle exactly. Check your compressor connection (the 1\/4 inch NPT adapter is included) and confirm your wheelbase is within the 150 inch coverage before ordering. The chucks are closed-flow by design - that is what lets the system hold and equalise pressure across all four tyres.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eAPEX Design USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003e4-tyre inflation kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eX02-17-042-3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInflator\u003c\/td\u003e\n\u003ctd\u003eAPEX 90 PSI, slide-valve operation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLine\u003c\/td\u003e\n\u003ctd\u003e42 ft, 3\/8 in nylon braided (user cut)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChucks\u003c\/td\u003e\n\u003ctd\u003e4x closed flow push-on\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFittings\u003c\/td\u003e\n\u003ctd\u003e3x composite Y; 1\/4 in NPT adapter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eValves\u003c\/td\u003e\n\u003ctd\u003eStandard Schrader\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eWhy do I cut the hoses myself?\u003c\/h3\u003e\u003cp\u003eSo the harness matches your wheelbase exactly - full-length lines on a short vehicle drag and snag.
