The kit's single biggest reason to buy is how it pairs a dedicated regulator and a 220 PSI gauge with a 1\/4 quick connect coupler so the compressor can clear freshwater lines without risking overpressure. It is a practical, do-it-yourself solution that reduces the risk of costly freeze damage in spring.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eModel compatibility:\u003c\/strong\u003e Designed specifically to be used with VIAIR 400P-RV or 450P-RV compressors so users get a proper fit and reliable performance.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003ePressure control:\u003c\/strong\u003e The included regulator lets you limit output pressure, protecting water lines and fittings when blowing out the system.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eAccurate monitoring:\u003c\/strong\u003e A 220 PSI gauge provides a clear, immediate readout to confirm the compressor is operating within safe limits for winterization tasks.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eQuick connection:\u003c\/strong\u003e The 1\/4 quick connect coupler and stud (M, NPT) make attaching to the compressor fast and secure for field use while traveling or at the campsite.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eBlow out plug:\u003c\/strong\u003e The dedicated blow out plug threads into the water intake to allow direct removal of water from lines, simplifying the winterization process.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe VIAIR 90145 is best for owners of travel trailers, fifth wheels, and motorhomes who already have a VIAIR 400P-RV or 450P-RV compressor and want a compact kit to winterize freshwater systems themselves.
