ABOUT HELIXAL
Professional heat shrink tubing built for electricians, contractors, engineers, and anyone who needs wire protection they can trust the first time and every time after.
OUR MISSION
HELIXAL was built around one idea — that the connections holding critical systems together deserve protection that will not fail. Every wire join, every harness termination, every splice is a point of vulnerability. We make heat shrink tubing that closes that vulnerability permanently.
From marine bilge pumps that run in saltwater spray to automotive harnesses that cycle through engine heat every day, to industrial panels that carry hundreds of volts through demanding environments — we engineer heat shrink solutions that perform where it counts. Our products meet military specifications and are trusted by electricians, contractors, and engineers across the United States.
We stock all 13 sizes across three product lines, so you always have the right tubing for the job in front of you. No compromises. No special orders for the size you need. Just consistent, industrial-grade wire protection, available now, delivered fast.

CERTIFICATIONS & COMPLIANCE
WHAT WE MAKE
Heat shrink tubing works by applying heat to a specially formulated polymer tube, causing it to contract tightly around the substrate. Our dual wall products add a hot-melt adhesive inner layer that melts and flows into the substrate as the outer wall shrinks, creating a complete mechanical and environmental seal.
Dual Wall Adhesive
Maximum protection. Hot-melt adhesive inner lining creates a fully waterproof, environmentally sealed connection. Available in large bulk rolls from 3/32" to 2".
Single Wall
Clean, reliable insulation for everyday electrical and wiring applications. Consistent wall thickness, flame-retardant polyolefin in bulk rolls up to 120ft.
Dual Wall Adhesive
The same dual wall adhesive-lined protection in convenient 10ft packs. Ideal for service work, repairs, and applications requiring multiple sizes without full rolls.
Applications
One product. Every application where wires need to stay sealed, protected, and reliable.
Wire harness protection, battery terminal sealing, sensor connectors, and underhood cable management. Rated for continuous exposure to oil, fuel, and heat.
Saltwater-proof electrical connections, bilge pump wiring, navigation electronics, and below-deck cable runs. The adhesive inner wall keeps moisture out permanently.
Panel wiring, machine control connections, high-voltage cable terminations, and manufacturing floor equipment. Built to handle vibration, chemicals, and temperature cycling.
Home electrical repairs, workshop wiring projects, garden lighting, and cable management. Professional results on every job — no special tools required beyond a basic heat gun.
BUILT FOR REAL CONDITIONS
Marine
Saltwater & Moisture
Bilge pumps, navigation electronics, and deck wiring operate in constant humidity, salt spray, and vibration. Helixal dual wall adhesive tubing creates a waterproof seal that survives engine compartment heat, UV, and repeated wet-dry cycles.
Automotive
Heat, Vibration & Fuel
Engine bays expose wiring to extreme temperature cycles, fuel vapors, oil mist, and constant vibration. Our 3:1 dual wall tubing handles it all — maintaining insulation integrity where failure means a fire risk or a dead vehicle.
Industrial
High Voltage & Abrasion
Panel builders, machine shops, and industrial electricians work with high-voltage wiring that demands consistent, code-compliant insulation. Helixal tubing meets UL 224 standards and delivers flame-retardant, abrasion-resistant protection across all 13 sizes.
WHAT WE STAND FOR
Every tubing specification is exact. Shrink ratios, wall thicknesses, and adhesive formulations are held to tight tolerances. We do not approximate — we engineer.
Built to outlast the project, the season, and the next repair. Polyolefin construction resists UV degradation, chemical exposure, and thermal cycling without brittling or cracking.
You fit it once. It stays sealed for life. The hot-melt adhesive inner layer flows into connectors and irregularities, creating a bond that does not loosen under vibration or temperature swings.
Industrial materials, no shortcuts. Our tubing is UL 224 compliant, RoHS certified, and meets the demands of critical installations — from marine bilge wiring to high-voltage industrial panels.
