By using PTFE as a binder, these are excellent in chemicals resistance, heat resistance, handling property and flexibility. The gaskets do not contain any rubber, and retightening is possible since deterioration with age and hardening does not occur.

Compressed Fiber Sheets are sheet type gasket materials, where special rubber binder and a small amount of filler material are mixed with organic and inorganic fibers, and rolled & vulcanized.

These are Sheet Gaskets made of VALFRON (PTFE) with excellent chemicals resistance and nonadhesive property.

This is a marshmallow-like free-size sealing material, which has been improved to be flexible and high in toughness while maintaining PTFE’s excellent chemicals and heat resistance. Three types with different cross-sections are available: oval, flat, and round type.

This is a VALFRON (PTFE) envelope gasket using Compressed Non-Asbestos Fiber Sheet or Expanded Graphite Sheet as core material. Three types with different cores are available: N type, S type and H type, and there are also 3 envelope types.

Utilizing the characteristic of pure graphite sealing material VALQUAFOIL, these gaskets are excellent in heat, chemicals and radiation resistance. They are applicable to wide temperature ranges from extremely low to high temperatures.

Spiral Wound Gaskets use inorganic paper, VALQUAFOIL (expanded graphite) and VALFRON (PTFE) tapes as filler materials, and they exhibit good elasticity by means of a V-shaped hoop.

These are semi-metallic gaskets where the outside of core material (cushion material), such as heat resistant felt, is covered with metal sheet. Since they can be made into any shapes, they are ideal for irregular-shaped flanges or heat exchanger gaskets.

These gaskets are manufactured from cold rolled metal plate, and include flat gaskets made of metallic sheet which is processed into a specified dimension and shape, and serrated gaskets with concentric grooves to improve sealing property.

These gaskets are made of single metal to be used for ring joint flanges.

Metal-C rings are made of a coil spring covered with a thin metallic sheet such as aluminum sheet. As they can offer sealing with a low tightening force, the products can be used in the fields handling high temperature, ultra high vacuum, as well as in applications subject to extremely low temperature and high pressure.

Metal Hollow O-rings are made of thin metal pipe processed into circle or other specified shapes, with both ends welded together. Since they can offer sealing with a low tightening force as well as compact gasket joints can be designed, the products are used in various types of equipment for high temperature, high pressure and high vacuum applications.

VALQUATEX is rubber coated fabric which uses materials such as glass and ceramic fibers.

Synthetic Rubber Sheet Gasket processed into a specified flat shape. These gaskets are used for low pressure applications where adequate tightening force is not available.

Flame-Resistant Carbonized Fiber is made by heat treating polyacrylonitrile (PAN) fiber. It has excellent flame resistance and heat resistance as well as tough elasticity.

With the use of bulking treated yarn, these are better in flexibility and heat resistance (heat resisting temperature of 350°C) than conventional glass cloth, and are best suited for cladding material to be used in heat insulation and cold insulation work.

Made of ceramic fiber and excellent in flexibility and high temperature heat resistance, these are best suited for various types of sealing materials, as well as heat insulating material, shielding material and protective material. Since a small amount of organic fiber is included, some amount of smoke is generated at the initial stage of heating.
