It uses a bolted housing and an EPDM elastomeric gasket that forms a leak-tight seal without welding under the specified operating conditions. This coupling accommodates axial movement and misalignment and maintains a leak-tight connection within the product's stated temperature and pressure ratings for systems conveying air, chemical products, fuel, gas, oil, other hydrocarbons, solids, and water. It operates within a temperature range of -4 Degrees to 212 Degrees F and withstands a maximum internal pressure of 232 psi.\u003c\/p\u003e  \u003cp\u003eKey Features: \u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e- Material: 316 stainless steel with polished finish for corrosion resistance.\u003c\/li\u003e \u003cli\u003e- Nominal pipe size: 4 inches.\u003c\/li\u003e \u003cli\u003e- Overall length: approximately 3-11\/16 inches.\u003c\/li\u003e \u003cli\u003e- Seal included: standard EPDM gasket for leak-tight connections.\u003c\/li\u003e \u003cli\u003e- Bolt specifications: two 6mm hex bolts made of 316 stainless steel.\u003c\/li\u003e \u003cli\u003e- Movement type: axial to allow limited pipe movement.\u003c\/li\u003e \u003cli\u003e- Certified low lead compliance for potable water use.\u003c\/li\u003e \u003cli\u003e- Meets ASTM 1476, TY2, CL2 or CL3 standards.\u003c\/li\u003e \u003cli\u003e- Vacuum rating up to 28 inches of mercury.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STRAUB","offers":[{"title":"Default Title","offer_id":43321951617118,"sku":"G20900-SI","price":406.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/Z28I_tfo5oy_dd411e74-70b5-47f2-80f4-b3bd0d7bcd49.jpg?v=1789310454","url":"https:\/\/nationalboilersupply.com\/products\/straub-g20900-si-4-in-316-stainless-steel-grip-l-pipe-coupling-polished-finish-axial","provider":"National Boiler Supply","version":"1.0","type":"link"}
