A wire pulled through raw sheet metal will chafe against the edge for a thousand small vibrations, and one day the insulation gives way and the harness shorts against the chassis. The inexpensive answer is a sleeve: a silicone collar that sits in the hole, holds the cable off the metal, and seals the gap against dust and splash without a connector or a gasket.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#3a3a3a;margin:0 0 18px 0;\"\u003eThis is a straight tube sleeve with a 16.5mm inner bore for the wire bundle and a 30mm outer seat for the sheet metal hole, supplied five to a pack. The body is moulded silicone, which stays flexible from deep cold to engine bay heat, resists the oils and solvents that degrade cheap PVC, and does not harden into a brittle ring after a season of thermal cycling. The straight profile is deliberate: it presents a flat seat against the panel so the sleeve cannot be pulled through under cable tension, and it keeps the bundle running perpendicular to the panel instead of kinking at the exit point.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#3a3a3a;margin:0 0 18px 0;\"\u003eBecause the material is silicone rather than rubber, the sleeve can be installed after the harness is already terminated. The wall flexes enough to work the collar into the hole with a blunt tool, then returns to shape and grips. That single property is what makes it useful in repair work, where the alternative is depinning a connector to slide a grommet on from the free end.\u003c\/p\u003e\n\u003cp

wing, especially on retrofit work where the loom was built before the hole was drilled. Trailer and caravan builders use it at the point where the lighting cable leaves the chassis. Industrial panel builders use it on enclosure walls to keep cable bundles off a cut edge and to hold a dust seal. Machine shops retrofitting sensors to an existing frame use it because the alternative, depinning a connector to slide a closed grommet on, costs an hour of labour per harness. It is a small part with a narrow job, and it does that job for the whole life of the machine.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-faq\" style=\"margin-top:32px;\"\u003e\n\u003ch3 style=\"font-size:19px;letter-spacing:.04em;text-transform:uppercase;margin:0 0 14px 0;color:#1a1a1a;\"\u003eQuestions Worth Asking\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom:16px;\"\u003e\n\u003cp style=\"margin:0 0 5px 0;font-size:15px;font-weight:600;color:#1a1a1a;\"\u003eWill it fit my panel hole?\u003c\/p\u003e\n\u003cp style=\"margin:0;font-size:15px;line-height:1.7;color:#4a4a4a;\"\u003eThe sleeve seats into a 30mm hole and passes a wire bundle up to 16.5mm in diameter. Measure both the hole and the bundle, not just one: a 30mm hole with a 20mm bundle will leave the cable loose inside the sleeve.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:16px;\"\u003e\n\u003cp style=\"margin:0 0 5px 0;font-size:15px;font-weight:600;color:#1a1a1a;\"\u003eCan I install it without cutting the wires?\u003c\/p\u003e\n\u003cp style=\"margin:0;font-size:15px;line-height:1.7;color:#4a4a4a;\"\u003eYes.
