When a line needs to be capped or a valve manifold requires sealing, waiting on back-ordered components is not an option for your business. Supply shortages often strike when project deadlines are tightest; causing failed inspections and frustrated clients. By securing high-quality Lesso Schedule 80 blind flanges now, you ensure that your crews remain productive and your systems stay operational when summer heat puts maximum demand on your infrastructure. Planning ahead with robust sealing components transforms a potential emergency into a routine maintenance task.\u003c\/p\u003e\u003cp\u003eThe Lesso Schedule 80 PVC blind flange offers a significant technical advantage over standard Schedule 40 or lower-grade alternatives. Designed to withstand higher pressure ratings and provide superior chemical resistance, these heavy-duty fittings reduce long-term maintenance costs and prevent the stress fractures common in thinner-walled components. The thicker cross-section provides a more stable bolting surface, which eliminates bowing and ensures a leak-proof seal even under fluctuating thermal conditions. Maintaining a stock of these professional-grade flanges gives your firm a competitive edge by allowing for immediate system modifications without the cost of specialized labor or emergency shipping fees.\u003c\/p\u003e\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh-Density PVC (Polyvinyl Chloride)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSchedule Rating\u003c\/td\u003e\n\u003ctd\u003eSchedule 80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWall Thickness\u003c\/td\u003e\n\u003ctd\u003eHeavy-duty industrial grade\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003eFlanged (Blind)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd\u003eVaries by size; typically handles 150 PSI at 73°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\/Finish\u003c\/td\u003e\n\u003ctd\u003eDark Gray \/ Industrial Matte\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompliance\u003c\/td\u003e\n\u003ctd\u003eASTM D1784 and ASTM D2467 standards\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eLesso\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eLesso Schedule 80 blind flanges are typically available in standard pipe sizes ranging from 2 inch up to 12 inch diameters to fit common industrial and commercial bolt patterns.

Tighten the bolts in a star pattern sequence to distribute pressure evenly across the flange face and prevent cracking due to point-loading. Ensure that all hardware is compatible with the environment, such as stainless steel for corrosive fertigation areas. It is critical to adhere to local plumbing codes regarding flange support and to never exceed the pressure rating as de-rated for elevated temperatures or surges.\u003c\/p\u003e","brand":"Lesso","offers":[{"title":"2-1\/2\"","offer_id":52023028285729,"sku":"853-025","price":67.77,"currency_code":"USD","in_stock":false},{"title":"3\"","offer_id":52023028318497,"sku":"853-030","price":81.78,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/Sch80_BLIND_FLANGE_1.png?v=1763586738","url":"https:\/\/asiwsupply.com\/products\/sch80-blind-flange","provider":"ASIW","version":"1.0","type":"link"}
