Kit Standard

Certified penetration for every vessel

Designed for any exhaust pipe at high temperature. Compact and easy to install, it reduces heat dispersion on the surrounding surface. Delivered pre-assembled, one weld, certified. Delivers A60 fire resistance up to 1,000 °C for 60 minutes.

MED A60 CertifiedWatertight 2 bar for 60 minDN32 to DN1000

Zero Welding

Kit Slim

Flangeless install, zero welding

Designed for exhaust pipe lines without pre-existing flanges. The V-Band clamp allows installation on any pipe type with zero welding and minimal footprint. Delivered pre-assembled, certified, ready to fit in a single operation. Delivers A60 fire resistance up to 1,000 °C for 60 minutes. Available for DN32 to DN1000.

V-Band connectionNo welding requiredAny pipe type

Rotary Flange

Kit Rotary

Rotating flange for faster exhaust alignment

Designed for exhaust pipe lines where the outlet angle is not fixed in advance. The rotary flange turns freely on the passage body, so the fitting adapts to the exhaust pipe run. Delivered pre-assembled, certified. Delivers A60 fire resistance up to 1,000 °C for 60 minutes. Available for DN32 to DN200 at no extra cost; larger diameters on request.
