DIRECT FROM THE SOURCE
Most “heat shrink manufacturers” you find are resellers
Search heat shrink tubing manufacturer and most results are distributors, catalog resellers, or marketplace listings — each adding a margin between you and the extruder. Helixal is different: we specify and manufacture the tubing, lot-test it, and sell it direct at helixalindustrial.com. When you order, you deal with the people who make it.
That means manufacturer pricing on every size, consistent supply across all 39 SKUs from one source, and documentation — UL 224, RoHS, lot data — straight from us. It is why electricians, auto and marine shops, solar installers, and distributors across the USA and Canada buy Helixal direct.
MANUFACTURING CAPABILITY
What we make, and how it’s built
Dual-Wall Co-Extrusion
Our 3:1 line is co-extruded — an abrasion-resistant polyolefin outer wall bonded to a hot-melt adhesive inner wall that flows and seals on heating. Manufactured to a 3:1 shrink ratio for a non-slip grip that 2:1 tubing cannot match.
39 SKUs, One Source
13 diameters from 3/32" to 2", across 3 product lines — 3:1 dual wall large rolls, 2:1 polyolefin large rolls, and 3:1 10ft packs. A complete size range from a single manufacturer, so procurement stays simple.
Lot-Tested, Not Spot-Checked
Every production lot is tested for shrink ratio, wall integrity, dielectric strength, and adhesive flow before release. Lot documentation is available to trade and distribution customers.
Built to UL 224 & RoHS
Manufactured to the UL 224 standard for extruded insulating tubing and RoHS-compliant — 600V rated, −55°C to +125°C, flame-retardant, and resistant to fuel, chemicals, and UV.

MANUFACTURER FAQ
Common questions
Is Helixal a heat shrink tubing manufacturer?
Yes. Helixal manufactures professional-grade heat shrink tubing to its own specification — 3:1 dual wall adhesive-lined and 2:1 polyolefin — across 13 sizes and 39 SKUs. Every lot is tested to UL 224 and RoHS standards before it ships direct from US fulfillment centers, with no distributor markup in between.
Does Helixal manufacture adhesive-lined (dual wall) heat shrink tubing?
Yes. Our 3:1 dual wall line is co-extruded with an abrasion-resistant polyolefin outer wall and a hot-melt adhesive inner wall. On heating, the adhesive flows and cools into a 360° waterproof, oil-proof, corrosion-resistant seal — purpose-built for marine, automotive, and outdoor wiring.
Can I buy heat shrink tubing direct from the manufacturer in the USA?
Yes. Helixal sells direct at helixalindustrial.com and ships from US fulfillment centers — no marketplace or distributor in between. Trade buyers, OEMs, and distributors can order any of the 39 SKUs at volume pricing by contacting us on WhatsApp or by email.
Does Helixal offer OEM or private-label heat shrink tubing?
Yes. As the manufacturer, Helixal supports OEM and private-label supply — bulk quantities across the full size range, with packaging and labeling to your specification for resale or inclusion in your own kits and assemblies. Contact our sales team to discuss volumes and lead times.
What certifications does Helixal heat shrink tubing carry?
Helixal tubing is manufactured to UL 224 (the Underwriters Laboratories standard for extruded insulating tubing) and is RoHS compliant, rated to 600V and −55°C to +125°C. Certificates and lot documentation are available to trade and distribution customers on request.
What sizes does the manufacturer produce?
All 13 diameters from 3/32" to 2" — covering wire gauges from roughly 26 AWG up to 4/0 AWG — across three lines: 3:1 dual wall adhesive-lined large rolls, 2:1 standard polyolefin large rolls, and 3:1 dual wall 10ft packs. That is 39 SKUs in total.
