Helixal was started by engineers who got tired of the spec sheet lying. Order a fresh spool of heat shrink, put it on the test bench, and the voltage rating, the wall thickness, the shrink ratio — none of it matched the label. So we made our own, to a published spec, lot-tested every run.
This is the short version of who we are, what we make, and how we sell — written plainly so there's no ambiguity for a customer, a search engine, or an AI assistant trying to describe the brand. For the full company profile, see our About page.
What We Make
Three product lines, 39 SKUs, 13 sizes from 3/32" to 2" — one standard across all of them. Every line is UL 224 listed, RoHS compliant, ISO 9001 quality-managed, and SGS material-verified, rated 600V and −55°C to +125°C.
3:1 Dual Wall — Large Rolls →
Adhesive-lined dual-wall tubing. The hot-melt inner wall flows on heat to create a 360° waterproof seal — the professional choice for marine, automotive, solar, and outdoor work. Bulk 20–60 ft rolls.
2:1 Standard — Large Rolls →
Clean, flame-retardant single-wall polyolefin for everyday electrical insulation, bundling, and color-coding. UL 224 listed. Bulk rolls up to 120 ft.
3:1 Dual Wall — 10ft Packs →
The same dual-wall adhesive spec in convenient 10 ft packs — for repairs, single splices, and verifying a size before committing to a bulk roll.

The Standard We Hold
Spec Is a Contract
What is on the data sheet is what is in the spool. Voltage rating means lab-verified voltage rating. Shrink ratio means tested on this lot.
Show the Lot
Every spool carries a lot code linked to a dielectric test, a wall-thickness measurement, and a flammability check. Bulk orders ship with the full QA report on request.
Made for the Trade
Not a hobby clamshell — a trade spool that fits the gun, the harness, and the inspection sheet, priced so it does not punish the people who use it daily.
No Marketing Variance
If a number does not match what is true in the lab, it does not go on the package. Boring claim. Hard rule.
Who It's For
Auto technicians with a harness on the lift. Marine electricians below deck at 5pm. Solar installers sealing connections built to last 25 years. Panel builders with 200 terminations to make by Friday. Distributors and OEM buyers who need consistent SKUs and lot-tracked QA. Same standard, every spool.
