Specs that match
the spec sheet.
Helixal was built by engineers who got tired of ordering a fresh spool of Helixal heat shrink tubing and finding the spec on the label had nothing to do with what came out of the test bench. So we made our own — to a published spec, lot-tested every run, sold direct at a price that doesn’t punish the trade.
Every spool of Helixal heat shrink ships with a lot code. That code corresponds to a dielectric test record, a wall thickness measurement, and a flammability check. If it is a Helixal spool, the lot is in our records. Every order ships through the same gate.
Three product lines: 2:1 heat shrink tubing for everyday electrical insulation, and 3:1 dual-wall adhesive-lined heat shrink for waterproof marine and automotive applications. Thirty-nine SKUs. One promise: spec sheet matches the catalogue matches the lab matches the field.
We don’t make heat shrink for the rack at the big-box store. We make it for the auto tech with a harness on the lift, the marine electrician below deck at 5pm, the panel builder with 200 terminations to make by Friday. Same standard. Every spool.

“I started Helixal because I got tired of specs that didn’t match the product. Every spool we ship is tied to a lab record — dielectric, wall thickness, flammability. We built this brand for the electrician who reads the spec sheet and expects the truth. That’s the only standard we ship to.”
What we
stand on.
Six rules.
They’re how every spool gets shipped.
Spec is a contract.
What's on the data sheet is what's in the spool. Voltage rating means lab-verified voltage rating. Shrink ratio means tested on this lot.
Same standard, every channel.
The 2:1 you order direct is the 2:1 we ship to wholesale. Same lot range. Same dielectric test. Same answer.
Made for the trade.
Not a hobby pack. Not a clamshell. A trade spool that fits the gun, the harness, and the inspection sheet.
Show the lot.
Every spool carries a lot code linked to a test record. Bulk orders ship with the full QA report on request.
One business day.
Bulk RFQ replies inside one business day. Direct orders are dispatched within 24 hours and reach you in 1–3 days.
No marketing variance.
If a number doesn't match what's true in the lab, it doesn't go on the package. Boring claim. Hard rule.
Three lines.
One standard.
