It carries a 2:1 shrink ratio and a dielectric strength of 600 volts per mil, making it suitable for protecting conductors and connections from abrasion, moisture, and common fluids or solvents. The tubing is flame retardant and rated for continuous operation from -67 degrees F to 275 degrees F, with a shrink activation range of 250 degrees F to 480 degrees F. Electricians and low-voltage technicians are the primary installers of this product.\u003c\/p\u003e\u003cp\u003eThe HST-375R is suited for above-ground electrical applications where insulation, strain relief, or color-coded marking of conductors is required. Typical use cases include terminating wire harnesses, protecting splices, and bundling multiconductor runs in residential, commercial, and light industrial wiring work. Each piece measures 3\/8 inch in diameter by 4 inches in length and is sold in packs with a minimum order quantity of 5.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2:1 shrink ratio for secure, form-fitting coverage over conductors and splices\u003c\/li\u003e\n\u003cli\u003eDielectric strength of 600 volts per mil for reliable electrical insulation\u003c\/li\u003e\n\u003cli\u003eFlame retardant thin-wall polyolefin construction\u003c\/li\u003e\n\u003cli\u003eContinuous operating range from -67 degrees F to 275 degrees F\u003c\/li\u003e\n\u003cli\u003eResists common fluids, solvents, abrasion, and moisture\u003c\/li\u003e\n\u003cli\u003eSuitable for cable insulation, wire marking, and bundling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose heat shrink sleeve for above-ground electrical wiring applications where 3\/8-inch diameter thin-wall tubing with a 2:1 shrink ratio is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed electricians or low-voltage technicians. Shut off and lock out all circuits before applying heat shrink tubing to any conductor or splice. Use an appropriate heat gun rated for the required shrink temperature range; open flame is not recommended as it may damage the tubing or surrounding materials. This product is rated for above-ground use only and should not be used in direct burial or submerged applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyolefin (Thin-Wall)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShrink Ratio\u003c\/strong\u003e: 2:1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDielectric Strength\u003c\/strong\u003e: 600 V\/Mil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Operating Temperature\u003c\/strong\u003e: -67 degrees F \/ -55 degrees C to 275 degrees F \/ 135 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShrink Temperature Range\u003c\/strong\u003e: 250 degrees F \/ 120 degrees C to 480 degrees F \/ 250 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlame Retardant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Above Ground Use Only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.032 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GARDNER BENDER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HST-375R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER BENDER","offers":[{"title":"Default Title","offer_id":51344688382258,"sku":"HST-375R","price":22.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310548916.jpg?v=1782040430","url":"https:\/\/voomisupply.com\/products\/gardner-bender-hst-375r-heat-shrink-tubing-3-8x4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
