Check the O-rings and thread seals periodically for wear and replace them if damaged. Keep the exterior clean to prevent buildup that could compromise the seal. With proper care, this housing provides extended service life, reducing total cost of ownership. The stainless steel sleeve resists corrosion, while the aluminum body offers lightweight durability—minimizing maintenance frequency and downtime.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore ordering the 21000-34-00-20-095-04-02, verify that your existing system requires a 3300 XL 8 mm probe and that the mounting thread (3\/4-14 NPT) matches your installation. If your application requires a different standoff adapter or penetration depth, please review other suffix options in the 21000 series. For a reliable supply of genuine Bently Nevada parts, PLC Source PRO offers this model new in factory packing with a 12-month warranty. Ensure you have the correct probe and cable length to complete your setup.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default","offer_id":44439640440931,"sku":"21000-34-00-20-095-04-02","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/8635\/0435\/files\/21000-34-10-20-058-04-02__E5_89_AF_E6_9C_AC_2834f41f-e2c9-4bd5-a959-c6b78cf568f7.jpg?v=1785881632","url":"https:\/\/www.plcsourcepro.com\/ar\/products\/bently-nevada-21000-34-00-20-095-04-02-proximity-probe-housing-assembly","provider":"PLC Source PRO","version":"1.0","type":"link"}
