Raychem Torches and Accessories for Heat Shrink Installation: Which Torch to Use

Which torch do you need for Raychem heat shrink products?

It depends on the product size. A small torch is fine for low voltage work and smaller high voltage accessories. Thick-wall sleeves and large splices need more heat. Raychem sells three torch setups that cover this range.

FH-2618A-1 torch kit

A light, portable torch for low voltage products and smaller conductor sizes in high voltage accessories up to 15 kV. It runs off disposable 14.1 oz propane cylinders. The handle and torch head are not sold separately. If you only need to replace the regulator and hose, that part is AD-3015-04 (details below). View the FH-2618A-1 torch kit in our store.

FH-2629 torch

A general-purpose, heavy-duty propane torch with a built-in igniter and a comfortable grip. It gives a clean-burning flame for shrinking high voltage products or thick-wall low voltage products. Buy the FH-2629-TORCH ASSY on its own if you already have a hose and regulator, or the FH-2629-KIT if you want the hose and regulator with it.

How to choose a Raychem torch

  1. Check the product. Low voltage and anything up to 15 kV with smaller conductors: FH-2618A-1.
  2. Thick-wall sleeves or higher voltage products: FH-2629.
  3. Large splices, Raysulate products, or frequent use in the field: FH-2649-PS-KIT.
  4. Match the hose to the job. A longer hose (25 ft or 30 ft) helps in manholes and vaults.
  5. Add a regulator with a gauge if your kit doesn't have one.

Frequently asked questions

What size torch do I need for heat shrink?

Use about 20,000 BTU/hr for low voltage and smaller high voltage products up to 15 kV (FH-2618A-1). Use about 30,000 BTU/hr for high voltage and thick-wall products (FH-2629). Large products are easier with the 90,000 BTU/hr FH-2649-PS-KIT.

Can I use a disposable propane cylinder?

Yes. The FH-2618A-1 is built for disposable 14.1 oz cylinders. The FH-2649-PS-KIT has a smaller burner and adapter available for disposable bottles.

Do I need a regulator?

Yes. All the torch kits use one. The FH-2618A-1, FH-2629-KIT and FH-2649-PS-KIT include it. For the FH-2629-TORCH ASSY alone, add the AD-GR340. To replace the regulator and hose on an FH-2618A-1, order the AD-3015-04.

What does auto ignite and auto shut-off do?

The Sievert-Matic S handle in the FH-2649-PS-KIT has a piezo igniter to light the flame and shuts off automatically.
