It is built with a 6 PSI trip point and a normally closed contact design, making it suitable for wiring into oil pressure warning lights, buzzers, or gauge systems on a marine engine. The switch threads directly into the engine block or oil gallery using a 1\/8 inch - 27 NPT fitting and connects to the boat's wiring harness through a 10-32 stud terminal, allowing for a straightforward electrical connection without special connectors.\u003c\/p\u003e\u003cp\u003eConstructed from stainless steel, the OP22900 is built to hold up in the marine environment where corrosion resistance matters for long-term reliability. It is compatible with marine engine control systems and gauges, and works as part of a broader engine monitoring or audible warning setup. The switch is compact and lightweight at 0.31 pounds, and is finished in white.\u003c\/p\u003e\u003cp\u003eThis switch is sold as a single unit and is intended as a direct-fit replacement or new installation part for boats using a 6 PSI trip oil pressure warning switch with a 1\/8 inch - 27 NPT thread and 10-32 stud terminal.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e OP22900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Oil Pressure Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Pressure:\u003c\/strong\u003e 6 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Normally Closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 1\/8 inch - 27 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e 10-32 stud\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282368357\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.31 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat pressure does the Sierra OP22900 oil pressure switch trip at?\u003c\/strong\u003e The Sierra OP22900 trips at 6 PSI, making it suited for engines that use a lower oil pressure threshold for their warning circuit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the OP22900 a normally open or normally closed switch?\u003c\/strong\u003e It is a normally closed switch, which is the contact configuration used for the 6 PSI trip point on the Sierra OP22900.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the OP22900 oil pressure switch use?\u003c\/strong\u003e It uses a 1\/8 inch - 27 NPT thread, allowing the Sierra OP22900 to install directly into a threaded oil pressure port on the engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of electrical terminal does this switch have?\u003c\/strong\u003e A 10-32 stud terminal is used on the Sierra OP22900, providing a simple connection point for the warning circuit wiring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra OP22900 oil pressure switch made from?\u003c\/strong\u003e Stainless steel is used for the OP22900, chosen for its resistance to corrosion in the marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the OP22900 oil pressure switch weigh?\u003c\/strong\u003e 0.31 pounds is the weight of the Sierra OP22900 oil pressure switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the Sierra OP22900 and the OP22891 switch?\u003c\/strong\u003e The OP22900 trips at 6 PSI while the OP22891 is a 15 PSI trip switch; both are normally closed and share the same 1\/8 inch - 27 NPT thread, but they are separate part numbers for different trip pressure requirements.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the OP22900?\u003c\/strong\u003e The Sierra OP22900 ships as a single oil pressure switch unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the OP22900 switch compatible with marine engine warning systems and gauges?\u003c\/strong\u003e Yes, the OP22900 is compatible with marine engine control systems and gauges, allowing it to be wired into an oil pressure warning light, buzzer, or gauge circuit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra OP22900 oil pressure switch?\u003c\/strong\u003e White is the color of the OP22900 switch housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the OP22900 be used with an audible warning buzzer?\u003c\/strong\u003e Yes, the normally closed contact design of the OP22900 allows it to be wired into an audible warning buzzer circuit as part of an engine monitoring setup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the OP22900 require any special connector for wiring?\u003c\/strong\u003e No special connector is needed; the OP22900 uses a standard 10-32 stud terminal for direct wire connection.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988457861339,"sku":"SIE-OP22900","price":15.57,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/sierra_lg_2653__09089.1558134145.500.750.jpg?v=1785188290","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-op22900-marine-oil-pressure-switch-6-psi-trip-1-8-27-npt-with-10-32-stud-terminal","provider":"Good Vibes Marina","version":"1.0","type":"link"}
