TYPES OF CONSTRUCTION

GAMSPIR®

Manufactured from a spirally wound stainless steel tape and a fi ller. Standard thickness of a gasket is 4.5mm. A GAMSPIR gasket is applied in a tongue and groove fl ange joints (type C/D and E/F)

GAMSPIR® I

Made of a GAMSPIR gasket and connected with an inner ring. Such a solution prevents the gasket from highly aggressive or oxidizing media, as well as from excessive distortion caused by assembly clamp. GAMSPIR I is applied for fl ange joints type E/F.

GAMSPIR® O

Made of a GAMSPIR gasket and connected with an outer centring ring. Such a solution prevents the gasket from blowout in high pressures and from too strong compression of the gasket. Additionally it facilitates concentric assembly of the gasket.

GAMSPIR® IO

Made of a GAMSPIR gasket and connected with an inner and outer (centring) ring. Thanks to such a solution the gasket features very high resistance to compression and easy assembly. This version is recommended for fl at fl anges with coarse pads.
