Made from irradiated modified polyolefin, the tubing is semi-flexible to accommodate modest bends without kinking while maintaining a protective layer around conductors, splices, and connectors. When correctly installed with heat, RNF-100-3 shrinks to a final outside diameter of 9.5 mm (0.374 in), providing a snug sheath that resists abrasion and environmental exposure. The RNF-100 family is designed for automotive component protection, offering durable shielding against moisture, dust, and minor mechanical abrasion while preserving flexibility. The 4-BK-FSP variant denotes a black sleeving option in this series, aligning with TE's Raychem heat-shrink portfolio and standard installation practices for automotive and electrical assemblies.\u003c\/p\u003e\u003c\/div\u003e","brand":"TE","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46243118317802,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-009.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/te-connectivity-rnf-100-3-4-bk-fsp-heat-shrink-tubing","provider":"GTG Hardware","version":"1.0","type":"link"}
