Product Selection

Select the product form first. WF and PO are non-shrinking tubes; SRG is braided insulation and WPET is expandable PET sleeving. WRSJD is installed as a sealing tape, WOLVO provides a grip covering and WRSGX protects fusion splices. WF remains a non-shrinking PTFE product and uses its own dimensions and material specification.

How to Specify Your Requirement

Identify the model first, then compare the supplied dimensions, fully recovered dimensions and installation space. Specify operating conditions, required flame or halogen performance, color, length, quantity and packaging. Certification and test references apply to the stated model and must be matched to the supplied product.

Dimensions are in mm unless another unit is stated. Operating temperature, minimum shrink temperature, full-recovery temperature and aging-test conditions describe different requirements. Keep them separate when selecting and installing the product.

Applications and Installation

Apply each product by its own construction: slide-on non-shrinking tubes, expandable or braided sleeves, wrap-applied adhesive tape, heat-recovered grip tubing, or reinforced fusion-splice sleeves. For WF ordinary PTFE tubing, use the dedicated PTFE product category as the primary website listing.

Frequently Asked Questions

Which model should I choose

Select the product form first. WF and PO are non-shrinking tubes; SRG is braided insulation and WPET is expandable PET sleeving. WRSJD is installed as a sealing tape, WOLVO provides a grip covering and WRSGX protects fusion splices. WF remains a non-shrinking PTFE product and uses its own dimensions and material specification.

Are all models flame retardant

Use the flame-performance statement of the exact model. Halogen-free, low-smoke and flame-retardant are separate requirements. A category title does not establish a shared rating.

How do I choose the size

Select the model and compare its supplied size with the largest assembly dimension and its recovered size with the required final fit. Check wall, tolerances, length and packaging in the corresponding table.

Is shrink temperature the operating temperature

No. Shrink or recovery temperature is an installation condition. Continuous operating temperature and short-duration laboratory aging or heat-shock tests are separate values.

Are all performance values guaranteed limits

Keep the distinction between standard requirements and typical test results shown in the tables. Agree the exact specification, acceptance limits, test method and product documentation with the order.

Can I order custom colors lengths or packaging

Send the exact model, dimensions, color, length, quantity and packaging requirements. Availability and nonstandard options are confirmed with the quotation.
