OUR RANGE OF KLINGER MAXIFLEX SPIRAL WOUND GASKET
KLINGER Maxiflex spiral wound gaskets combine the ease of sealing of a graphite, PTFE or mica filler with the strength afforded by a specially profiled metallic, spring-like reinforcement. The sealing element is manufactured by interleaving plies of alternating metallic winding strip and filler to create a gasket that is robust and easy to install. KLINGER Maxiflex spiral wound gaskets can be manufactured from a wide range of metals to resist chemical attack and temperature related degradation and used in combination with either graphite, PTFE or mica filler.
Properties of Maxiflex
- Creates a very leakight, reliable seal.
- Suitable for high temperatures and pressures.
- Can be manufactured to suit standard flanges and also custom-designed vessels.
Below are the most common gasket configurations.

KLINGER Maxiflex Pro
A high-integrity, dual-seal gasket specially designed for service in high-criticality, corrosive applications where sealing performance is of paramount importance.
- The KLINGER Maxiflex Pro gasket is designed for use in highly aggressive chemical applications such as hydrofluoric acid.
- The inner ring of a standard Maxiflex can allow media to accumulate between the flange and inner ring which could promote corrosion.
- Maxiflex Pro prevents this, the conformable facing material enables the gasket seal at the flange bore eliminating media build-up.
- The incorporation of a Maxiprofile inner ring creates a gasket with two sealing regions.
- The Maxiprofile also acts as a compression stop needed for high integrity gaskets and also enables a seal to be created inward of the spiral wound sealing element.
KLINGER Maxiflex Pro-X
- An addition to the Maxiflex Pro range designed for use in seawater applications where the graphite cannot be exposed to the media.
- The Mica filling on the inner and outer edges of the spiral stops permeation of the seawater to the graphite.
- Designed for a wide range of applications including hydrocarbons, fuels and seawater.
- Fire-safe to API-6FB.
