Product Catalogue

Wellele heat shrink sleeving range classified by material, wall type and application

Every listing below is a real Wellele part. Use the four routes (material, product type, application, installation method) to narrow down, then open the product page for the size table and datasheet notes.

By materialBy product typeBy applicationBy installation

Route 1 — By material

Material decides the baseline: chemical exposure points to fluoropolymer, sustained heat to silicone or fiberglass, cost-sensitive general purpose to polyolefin or PVC.

Polyolefin (PE)

Heat shrink · cable accessories · dual wall

Silicone rubber

Cold shrink · high-temperature tubing · tape

Fiberglass & silicone-coated fiberglass

Woven and extruded sleeving

Fluoropolymer (PTFE / FEP / PFA)

Chemical-resistant heat shrink

PVC & PET

Economy heat shrink · braided sleeve

Textile & composite

Wear strip · reflective · foil constructions

Polyimide-fiberglass & metal/thermoplastic assemblies

Special constructions

Full material notes live on the Materials hub: this page only routes.

Route 2 — By product type

Pick the construction form first if the installation method is already fixed on your side.

Heat shrink tubing

Single wall · dual wall adhesive · fluoropolymer

Cable accessories (heat & cold shrink systems)

Terminations · joints · stress control

Busbar insulation

Casing · snap-on · connection boxes

Braided & woven sleeving

Expandable · fixed braid · fiberglass

Rigid & shaped fiberglass sleeving

Extruded · corrugated · bellows · reflective

Tapes & wraps

Fiberglass · silicone · composite · foil

Wrap-around textile sleeves

Installed without disconnecting the harness

Molded parts & boots

End caps · breakout boots

Construction-level definitions are on the Product Types hub.

Route 3 — By application

Start from what the part must survive, not from the material name.

Wire harness protection

Abrasion · bundling · flexing

Abrasion on fixed routing → PET braid or textile wrap. Flex points → textile flexing sleeve. Harsh zones → fiberglass constructions. See the Wire Harness solution.

Cable joints & terminations

LV to 26/35 kV systems

Choose by voltage class and by whether the crew can use a heat source on site. See the Cable Joint solution.

Busbar & switchgear

Phase insulation · touch protection

Rectangular bar → casing sized on width × thickness. Retrofit without stripping the bus → snap-on tube. See the Busbar solution.

High-temperature zones

Furnace-adjacent · engine bay · foundry

Separate the heat mode first: continuous ambient, contact, radiant or splash. Constructions differ: see the Industrial solution.

Chemical exposure

Solvents · fuels · aggressive media

Fluoropolymer constructions are the default starting point; confirm the actual medium against the grade datasheet.

Coil & transformer wrapping

Mechanical reinforcement · varnish compatibility

Wrapping tape is reinforcement, not the main insulation layer. Check varnish wet-through on your system.

Sealing & environmental closure

Moisture · dust · end-of-cable

Adhesive-lined tubing, end caps and cold shrink all seal: the right one depends on the joint design and the rework expectation.

Scenario-level routing is on the Applications hub.

Route 4 — By installation method

The method you can actually run on site eliminates half the catalogue.

Heat gun / oven shrink

Requires a heat source and clearance

No-heat recovery

For heat-restricted areas

Slide-on / snap-on

No shrink step · retrofit friendly

Wrap / wind-on

Installed on finished assemblies

System-kit installation

Component sets for joints & terminations

Performance filters (dual wall, flame retardant, halogen-free, high temp, cold shrink) are on the Performance hub; voltage classes on the Voltage Rating hub; ratio selection on the Shrink Ratio hub.

Wellele Series & Type Index

Every Wellele listing carries a Series-Type code: a family (Series) plus a construction variant (Type). The same codes appear in the cross-reference tables on the individual product pages, so a competitor part number resolves to one Wellele Series-Type and then to the page below. Codes are catalogue references for identification only: they do not by themselves imply a certification, a dimensional interchangeability or a test equivalence. Confirm the values on the product page before ordering.
