RAYCHEM TMS PRINTABLE HEAT 3/4″ 250 PC BOX

Description

Raychem TMS Printable Heat Shrink Tubing — 3/4″ (250-Piece Box)

The TMS-SCE-3/4-2.0-4 is a 250-piece box of Raychem TMS (Thermal Marker Sleeve) printable heat shrink tubing in 3/4″ (approximately 19.1 mm expanded inner diameter). Raychem TMS is a laser-printable heat shrink marker sleeve used throughout professional motorsport harness construction for permanent, machine-printed circuit identification that replaces hand-written labels, colour-coded sleeves, and stick-on labels. TMS markers are suited to larger wire bundles, multi-conductor shielded cable terminations, and primary sub-harness identification.

What Is Raychem TMS Printable Heat Shrink?

Raychem TMS is a cross-linked polyolefin heat shrink tubing with a printable outer surface that accepts laser-printed text, circuit numbers, wire identification codes, and custom labels. The printed information is shrink-sealed onto the wire surface when heat is applied, making it permanent and resistant to abrasion, fuel, oil, and cleaning chemicals. This is the professional standard for motorsport harness wire marking — used by factory racing teams, aerospace harness manufacturers, and high-end motorsport harness builders as an alternative to hand-writing on cable ties or using generic colour-coded sleeves without specific identification.

Why Printed Wire Identification Matters in Motorsport

A professional motorsport harness is built to a wiring schematic that assigns a unique circuit number or identifier to every wire in the vehicle. Printing these identifiers onto TMS marker sleeves at every connector termination and breakout point allows any circuit to be traced instantly from any access point in the harness — whether during initial commissioning, fault diagnosis at the circuit, or post-crash harness inspection. The time saved during fault diagnosis at a race event by having permanently labelled circuits is significant; hand-written or improvised labelling methods are typically illegible after a season of fuel, oil, and vibration exposure.

3/4″ Size — Application Range

The 3/4″ TMS tubing suits larger wire bundles, multi-conductor shielded cable terminations, and primary sub-harness identification. Select the TMS size that, when shrunk, fits snugly over the wire insulation outer diameter — a correctly sized marker sleeve grips the wire firmly and remains in position at the correct location on the circuit rather than sliding along the wire under harness movement.
