Find the joint that best suits your needs
Type I
(±) Pressure
Textile joint for direct fixing to the duct using clamps. Suitable for air and gas ducts at medium temperature.
✓ Fast installation without flanges, using metal clamps.
✓ Temperature range: -5ºC to +400ºC depending on the selected textile material.
✓ Ideal for large diameters and custom geometries in ventilation and clean‑air systems.
Type II
(+) Pressure
Textile joint installed between backing flanges and counter‑flanges, especially recommended for positive pressure, air, gases and fumes.
✓ Robust fixing for systems with positive internal pressure difference.
✓ Extended temperature range: -5ºC to +525ºC, depending on the selected material.
✓ Used on boiler outlets, industrial ducts and process equipment.
Type III
(-) Pressure
Textile joint for fixing between counter‑flanges and backing flanges in negative‑pressure ducts. Especially designed for extraction and vacuum processes.
✓ Optimum tightness in systems with vacuum or fume and vapor extraction.
✓ Temperature range: -5ºC to +525ºC; multilayer fabrics for maximum durability.
✓ Applications: industrial chimneys, dust extractors and aggressive gases.
Type IV
(+) Pressure
Textile joint for installation between counter‑flanges parallel to the duct and external backing flanges, used on positive‑pressure lines and at extreme temperatures.
✓ Recommended for high temperatures up to +1,100ºC.
✓ Large sealing surface for large‑section ducts with complex geometry.
✓ Suitable for thermal plants, combustion systems and the steel industry.
Type V
(-) Pressure
Textile joint for installation between parallel counter‑flanges and external flanges, in negative‑pressure systems exposed to extreme temperatures.
✓ Maximum design flexibility for negative pressure and demanding thermal cycles.
✓ Reinforced materials for highly corrosive environments and temperatures up to +1,100ºC.
✓ Commonly used in desulfurization, industrial filters, exhaust ducts and extraction systems.
