The outer wall is constructed from flame-retardant, flexible polyolefin that is selectively irradiation cross-linked for reliable shrink performance. An internal layer of thermoplastic adhesive provides a sealed, moisture-resistant barrier when heat is applied. Available in black and red, this tubing ships in four-foot lengths or six-inch cut pieces and meets MIL-I-23053\/4, Class 3 application specifications. Licensed electricians and electronics technicians install this product in both field and shop environments.\u003c\/p\u003e\n\u003cp\u003eThe EPS-300 series is suited for wire harnessing, connector back-sealing, and environmental protection of electrical terminations in residential, commercial, and industrial settings. The adhesive liner maintains high flow during shrink, allowing it to conform tightly around irregular geometries such as connector bodies and splices. A kit option containing 42 pieces of six-inch lengths in assorted sizes is also available for technicians who require a range of diameters on a single job. The tubing is appropriate for applications where moisture ingress, vibration, or mechanical abrasion is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-wall construction with flame-retardant polyolefin outer wall and internal thermoplastic adhesive liner\u003c\/li\u003e\n  \u003cli\u003eSelectively irradiation cross-linked outer wall for consistent, controlled shrink performance\u003c\/li\u003e\n  \u003cli\u003eAdhesive layer maintains high flow and strong adhesion characteristics during heat application\u003c\/li\u003e\n  \u003cli\u003eMeets MIL-I-23053\/4, Class 3 application specifications\u003c\/li\u003e\n  \u003cli\u003eAvailable in four-foot stick lengths and six-inch cut pieces; kit format includes 42 pieces in assorted sizes\u003c\/li\u003e\n  \u003cli\u003eStandard colors: black and red\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style environmental protection sleeve for electrical wire, cable, splices, and connector terminations requiring dual-wall heat shrink insulation per MIL-I-23053\/4, Class 3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed electricians or qualified electronics technicians. De-energize all circuits before applying heat shrink tubing to any termination or splice. Use a calibrated heat gun set to the appropriate shrink temperature; open flame tools are not recommended as they can damage the adhesive liner or char the polyolefin outer wall. Follow NEC guidelines for insulation and conductor protection where applicable.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Series\u003c\/strong\u003e: EPS-300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Dual-wall, thin-wall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Wall Material\u003c\/strong\u003e: Flame-retardant flexible polyolefin, irradiation cross-linked\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Layer\u003c\/strong\u003e: Thermoplastic adhesive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard Colors\u003c\/strong\u003e: Black, Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard Lengths\u003c\/strong\u003e: 48-inch sticks and 6-inch cut pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication Specification\u003c\/strong\u003e: MIL-I-23053\/4, Class 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.34 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051135384442\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000132720\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344731799858,"sku":"7000132720","price":1060.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310532051.jpg?v=1782041933","url":"https:\/\/voomisupply.com\/products\/3m-7000132720-eps-300-dual-wall-heat-shrink-tubing","provider":"Voomi Supply","version":"1.0","type":"link"}
