GST-Industry is located in Nanjing nearby Shanghai and has a professional division for sale of sealing materials and a cutting center, which offers different types of gasket cutting services of all kinds for customers in the market. Now many professionals look to GST-Industry as the single source for all their cutting solutions. Usually it includes soft cut, metallic and semi-metallic gaskets based on different standards like ANSI, GB and drawings. For cutting gaskets, various materials are used such as: Non-Asbestos Fibre, Composite Gaskets, Metallic & Semi-Metallic, PTFE and Natural/Synthetic rubbers. Most of the requirements are according to design. In general, die cut and CAD/CAM machines are used as per samples and drawings.

◆ KLINGERsil C-4243
C-4243 is universal gasket material for general applications of liquids and gases at lower pressure and temperatures. Good chemical resistance against water and oil.
KLINGERsil C-4243 meets the requirements of BS 7531. C-4243 also has KTW, DIN-DVGW and Germanischer Lloyd approval.
◆ KLINGERsil C-4324
C-4324 is a cost effective grade material with very good mechanical strength often used for general purpose applications. Based on a blend of glass, aramid and carbon fibres bonded with NBR rubber C-4324 has good resistance to oils, fuels, hydrocarbons, water, low pressure steam and also for weak acids and alkalis.
KLINGERsil C-4324 meets the requirements of BS 7531 Grade Y, WRAS approved for use with potable water.
◆ KLINGERsil C-4500
C-4500 is a premium grade material based on carbon fibre with NBR binder designed for use with higher temperatures and pressures than the majority of calendared materials. The use of carbon fibres increases resistance to temperature related aging and to attack when used in alkaline services. C-4500 is fire-safe.
KLINGERsil C-4500 meets the requirements of BS 7531 Grade X and is also fire-safe. C-4500 also has TA-Luft (Clean Air) approval.
◆ KLINGERsil C-4400
C-4400 is a high grade material manufactured from aramid fibres with NBR binder commonly used in the automotive and aerospace industries.
KLINGERsil C-4400 meets the requirements of BS 7531 Grade Y and has TA-Luft (Clean Air) approval.
◆ KLINGERsil C-8200
C-8200 is a compressed fibre material developed to be used with a broad range of chemicals with particularly good resistance to strong acids and alkalis. C-8200 is a economical alternative to PTFE based materials in applications are less aggressive.
C-8200 has TA-Luft (Clean Air) approval.
◆ KLINGERsil C-6327
C-6327 is a specialist material developed for use in the refrigerating industry. C-6327 is manufactured with aramid fibres with a blend of Styrene Butadiene Rubber (SBR). The blended binder system gives the material good controlled swell properties in oils, water and fuels enabling good gasket tightness even with low installation loads.
◆ KLINGERsil C-4500/4509
C-4500 is a premium quality high-pressure gasket especially suitable for use with high temperature alkaline media and superheated steam. A superior performance product designed for use in the chemical industry. C-4509 is an expanded steel reinforced version of C-4500 which increases the compressive strength and in turn the maximum pressure capability. The increased stability provided by the reinforcement also allows this material to be used for increased temperatures with greater resistance to thermal degradation.

Our finished products from Klinger: Metallic Gaskets

Klinger manufacture a range of metallic gaskets including:
◆ Maxiflex spiral wound
◆ Maxiprofile coated grooved metal
◆ Maxigraph covered, corrugated metal
◆ Ring type joints

These gaskets, along with the older style jacketed gaskets are widely used in petrochemical applications. Metallic gaskets often utilise a soft sealing media such as graphite used in conjunction with the metal to create a high-strength, high-integrity gasket able to create joints with very high leaktightness.

Klinger can manufacture metallic gaskets in a wide range of alloys to cover even the most chemically aggressive applications.
