Sievert Light Line 871601 – 8716 Neck & Valve Assembly for Primus 2000 & Calor 340
A brass neck and valve assembly that connects directly to a Primus 2000 or Calor 340 gas cylinder — no hose or regulator required. Needle valve for precise flame control, back pressure valve to reduce flare-up risk. Accepts M8 × 0.75 thread burners from the Sievert Light Line range (8725, 8719, 8720, 8842). 178 × 27 × 86mm, 136g. Steel handle.
The Sievert 8716 Light Line assembly is the compact, cylinder-mounted torch system — where the Pro 86 and Promatic handle systems connect via a hose and regulator, the 8716 screws directly onto the top of a Primus 2000 or Calor 340 cartridge cylinder. This makes it an ultracompact, portable torch solution with no hose to manage and no separate regulator to fit. The needle valve provides precise flame adjustment and the back pressure valve reduces the risk of flare-up on ignition. Burners from the Sievert Light Line range (8725, 8719, 8720 and 8842) thread directly onto the M8 × 0.75 outlet of the 8716 assembly. Burners are sold separately.
