You're dealing with outdoor sensor arrays or automotive harnesses where moisture just kills signal integrity, and what these do is give you a fully sealed joint that passes IP68 testing—no more chasing intermittent failures under hood.
0.1 to 6.0mm² covers everything from tiny thermocouple leads to main power feeds, and the color bands let you grab the right gauge without squinting at print, which saves time when you're running three separate harnesses at once.
We injection-mold the polymer sleeve so the bead of solder stays centered in the barrel; it's a small detail but means less rework on crimps that don't quite align with the heating zone, usually about 150°C hot air gun setting.
600V rating and RoHS compliance are standerd, but what you don't see on the spec sheet is that teh tubes shrink hard enough to resist diesel dip and brake cleaner sprays—I've seen these survive pressrue washing stations where regular butt splices fail by week three.
Custom packging takes about 20 days or so form order, though we usually stock the 100-piece packs in white, red, blue, and yellow, so for a first run just tell me which sizes you need and I'll have the samples out within a week.
The shrink temperature is 150°C, so you’ll need a heat gun or similar hot air tool to activate the shrink tubing. A standard lighter isn’t recommended because it won’t heat evenly and could damage the polymer.
Yes, once properly heated and shrunk, the dual-hole design and heat shrinkable polymer create a watertight seal rated IP68. That means they can handle submersion in up to 1.5 meters of water for 30 minutes without leaking.
Absolutely, the standard pack is 100 pieces, but we can customize the packaging quantity to fit your needs. Just let us know how many per pack you want when placing your order.
Yes, they are RoHS and REACH compliant, and we can provide the relevant certificates or test reports upon request. Just ask your sales contact for the docs.
The MOQ is typically 10 packs (1000 pieces total) for standard orders, but we can be flexible for trial orders. If you need a smaller quantity first, reach out and we’ll work something out.
