The stopper tapers from a small-end diameter of 1-1\/64 inches to a large-end diameter of 1-17\/64 inches, with a projection of 1.266 inches. It is molded from solid black rubber and carries a Shore A durometer hardness range of 38 to 48, providing a compressible, resilient fit across a variety of neck and bore sizes. Lab technicians, plumbers, and maintenance professionals install these stoppers for pressure testing, flow isolation, and equipment sealing.\u003c\/p\u003e\u003cp\u003eSize 6 tapered rubber stoppers are commonly used in laboratory settings to seal round-bottom flasks, test tubes, and Erlenmeyer flasks, as well as in industrial and plumbing applications for pipe end plugging and pressure testing. The black rubber construction suits general-purpose use where chemical splash resistance and a snug mechanical seal are needed. These stoppers are sold in a package quantity of 20, making them suitable for shop stock or high-turnover lab environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTapered profile fits Size 6 openings with a small end of 1-1\/64 inches and large end of 1-17\/64 inches\u003c\/li\u003e\n\u003cli\u003eShore A durometer range of 38 to 48 for compressible, secure seating in varied bore sizes\u003c\/li\u003e\n\u003cli\u003e1.266-inch projection provides adequate grip depth and pull-out resistance\u003c\/li\u003e\n\u003cli\u003eBlack rubber construction offers general chemical and fluid resistance\u003c\/li\u003e\n\u003cli\u003ePackage of 20 units supports shop stock and bulk lab use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-stock tapered rubber stopper for Size 6 openings in laboratory glassware, industrial containers, and pipe test applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert by hand with a twisting motion to seat the stopper fully into the neck or bore opening. Do not use tools that could puncture or deform the rubber. For pressure-test applications, verify that the stopper durometer and taper are appropriate for the pressure rating of the system being tested before applying any load. Discard stoppers that show cracking, swelling, or permanent deformation from prior chemical exposure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStopper Size\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1-1\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 1-17\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1.266 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShore A Durometer Hardness\u003c\/strong\u003e: 38 to 48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ITRS-6-BKN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720372060466,"sku":"ITRS-6-BKN","price":39.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d687488643fc0d06d21988d8aa41a4fe.jpg?v=1788562917","url":"https:\/\/voomisupply.com\/products\/value-collection-itrs-6-bkn-tapered-rubber-stopper-size-6","provider":"Voomi Supply","version":"1.0","type":"link"}
