Leister Silicone Rubber Pressure Roller, 40 mm Green Roller for Hot-Air Welding

This Leister silicone rubber pressure roller is a hand tool for pressing and sealing thermoplastic roofing membrane seams after hot-air welding. The green 40 mm silicone roller rides along the weld edge to bond lap seams evenly. Sold as one piece, it pairs with Leister hot-air tools like the TRIAC and VARIMAT line.

Key Features:

  • Seams seams tight: Silicone rubber roller presses membrane laps immediately after hot-air welding to create a uniform, void-free seam.
  • 40 mm width: The 40 mm roller width matches standard roofing seam geometry for single-ply membrane work.
  • Heat resistant: Silicone rubber construction tolerates contact with freshly welded, still-hot membrane.
  • Green roller: Green silicone roller cover distinguishes it from other rollers in the welder's kit.
  • Genuine Leister: Genuine Leister replacement tool, manufacturer part 161.156.
  • Single piece: Sold per piece for easy replacement or spare-kit stocking.

Expert Verdict — Reviewed by the SuperArbor Pro Desk

Keep a dedicated seam roller in hand before you strike the weld; seams must be pressed within seconds of hot-air welding for a proper bond. A 40 mm silicone roller is the standard width for single-ply TPO and PVC lap work. Inspect the roller face regularly for hardened or contaminated silicone and replace it to avoid seam defects.

Seams are hot immediately after welding; wear gloves and avoid touching the weld area with bare skin.
