Each piece measures 0.75 inches in diameter before shrinking and 4 inches in length, shrinking down to approximately 0.375 inches to create a tight, protective sleeve. The tubing is flame retardant and formulated to resist common fluids and solvents, making it suitable for use in HVAC, plumbing, pool, and general electrical service work where moisture and chemical exposure are concerns. Licensed electricians, HVAC technicians, and service professionals keep this tubing on hand for clean, code-compliant terminations and repairs.\u003c\/p\u003e\n\u003cp\u003eThis heat shrink tubing is suited for residential and light commercial electrical work, including wire splices, terminal insulation, and connector protection. It performs well in environments where exposure to oils, cleaning solvents, or moisture is common, such as HVAC equipment panels, conduit runs, pool control wiring, and pump motor leads. The 2-piece pack is practical for single-job use or topping off a service kit without carrying bulk stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlame retardant construction for use in code-sensitive electrical applications\u003c\/li\u003e\n  \u003cli\u003eResists common fluids and solvents for durability in wet or chemical-exposed environments\u003c\/li\u003e\n  \u003cli\u003e2:1 shrink ratio shrinks from 0.75 inches down to approximately 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e4-inch length provides adequate coverage for most splice and terminal applications\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-piece pack, convenient for field service and spot repairs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose heat shrink tubing solution compatible with standard wire gauges and terminals that fall within the 0.375 to 0.75 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed electricians or qualified HVAC and service technicians. De-energize and lock out the circuit before working on any wiring. Slide tubing onto the conductor before making the splice or terminal connection, then position over the joint and apply heat evenly using a heat gun, avoiding open flame. Do not overheat, as excessive temperature can damage insulation or underlying conductors.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePre-Shrink Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePost-Shrink Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlame Retardant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical Resistance\u003c\/strong\u003e: Resists common fluids and solvents\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ECM INDUSTRIES LLC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HST-750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER BENDER","offers":[{"title":"Default Title","offer_id":51560953086258,"sku":"HST-750","price":33.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16b77d0a245aa23ac3d7f34b5b59f43c.jpg?v=1786459886","url":"https:\/\/voomisupply.com\/products\/ecm-industries-llc-hst-750-heat-shrink-tubing-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
