Discount Viair 90103 165/200 PSI Pressure Switch
great replacement for my switch...work great like my old one...i would suggest buying a couple if u plan on exposing it to the outdoors...I bought this to replace the factory switch for the VIAIR 20007 air source kit. It seems to hold pressure well and the unit seems like it is sealed better that the factory one. Has been in use for a couple of months with no issues yet. I installed the kit underhood where it is exposed to higher temperatures and the factory switch had 2 wires coming out of a rubber boot. It started leaking air around the wires within a couple months of installation, and you cant service it without damaging the whole switch. This replacement has 2 spade style connectors that appear to be able to hold up to higher underhood temps. A nice bonus is that if it does go bad its an easy swap out instead of having to cut wires and resolder everything. Just pop off the leads from the connectors and reinstall when done. Ive also read other sites that say these pressure switches are the weakest link in ANY automotive onboard air setups.
