Characteristics & Main Applications
Universal high-pressure gasket (C-super) for use in a wide range of industrial applications. Suitable for high stress due to wire reinforcement. Resistant to oils, water, steam, gases, fuels, alcohols, hydrocarbons, lubricants and refrigerants. KLINGER®SIL C-4408 is also known as C4408.
Gasket material based on NBR-bound aramide fibres.
The Klinger pT diagram provides guidelines for determining the suitability of a particular gasket material for a specific application based on the operating temperature and pressure only. Always refer to the chemical resistance of the gasket to the fluid.
1. In area one, the gasket material is normally suitable subject to chemical compatibility.

Function & Durability
The performance and service life of KLINGER gaskets depend in large measure on proper storage and fitting, factors beyond the manufacture’s control. We can, however, vouch for the excellent quality of our products. With this in mind, please also observe our installation instructions.

4 – FIRST AID MEASURES
- Inhalation : Dust arising from working the product should be treated as nuisance particulate material. Inhalation of dust may cause irritation to the mucous membranes and upper respiratory tract. Movement of exposed individual to fresh air is recommended.
- Skin : May cause irritation to individuals with sensitive skin. Wash skin with soap and water. Launder heavily contaminated clothing before reuse. If prolonged irritation occurs, seek medical advice.
- Eye : May cause mechanical irritation in contact with eyes. Remove small solid particles and rinse with water for a minimum of 15 minutes. In all cases of eye contamination it is a sensible precaution to seek medical advice.
- Ingestion : Not hazardous. Not a likely source of exposure. If ingested, give plenty of fluid to assist passage through system. Seek medical attention if irritation occurs.
5 – FIRE FIGHTING MEASURES
- Suitable Extinguishing Media : Water, carbon dioxide, powder extinguishers, foam extinguishers
- Hazards from Combustion Products : In case of combustion, the same gases are produced as with burning rubber. The following may be produced in case of fire: Carbon monoxide; carbon dioxide; sulphur oxides; nitrous gases (NOx); irritating/caustic, combustible as well as poisonous carbonisation gases.
- Precautions for Firefighters and Special Protective Equipment : Breathing apparatus and eye protection must be worn to protect from dust and fumes.
6 – ACCIDENTAL RELEASE MEASURES
- Emergency Procedures: Fire: See Section 5
Personal: See Section 4
Environmental: No known environmental hazards exist.
- Methods and Materials for Containment and Cleanup : Approved vacuum cleaners with high efficiency filters (HEPA) conforming to AS3544 or equivalent must be used to clean areas. Spills which involve powder, dusts or granules may create a slip hazard and should be cleaned up immediately. Sweep up but avoid generating dusts.
- Additional : In the case of improper use (see Section 8) fine dust may result. Adequate suction and filtering of the exhaust air should be ensured.
7 – HANDLING AND STORAGE
- Handling : No special precautions necessary when handling the material in its finished form However, whenever further processing of the product is undertaken, potential for the generation of dust exists. See Section 8.
- Storage : Store in a cool, dry, well ventilated area removed from foodstuffs. Material is only flammable through the effects of intensive heat. Excessive heat in the storage area may diminish the product’s performance in its intended application.
8 – EXPOSURE CONTROLS/PERSONAL PROTECTION
- National Exposure Standards (Time-Weighted Averages)
- Precipitated Silica: 10mg/m3 ES-TWA
- Nitrile Butadiene Rubber: 50ppm ES-TWA
- Aluminia Silicate: 10mg/m3 ES-TWA
- Aramid Fibre: 0.5fibre/mL ES-TWA
(Recommended – Note that Aramid fibre has no current assigned exposure standard, however as a general safety precaution the above guideline may be used.)
- Biological Limit Value : No Biological Limit Value allocated.
- Engineering Controls : Ensure adequate ventilation exists to maintain air concentrations below exposure standards. Do not inhale dust. Use localised extraction or wet methods of work to control dust levels.
- Personal Protective Equipment : No special precautions necessary when handling the material in its finished form. However, whenever further processing of gaskets is undertaken, the potential for the release of particulates that may cause mechanical abrasion exists. In the case of particle generation exceeding the above-noted National Exposure Standards, recommended PPE are rubber/PVC gloves, coveralls, safety glasses and a P2 particulate (AS1716 or equivalent) respirator. When removing embrittled or spent material or when high levels or dust exist a full-face class H particulate cartridge respirator or full-face positive pressure demand airline respirator (AS1716 or equivalent) is recommended. Good hygiene practices must always be maintained.

11 – TOXICOLOGICAL INFORMATION
The material in its finished form presents no known health hazard. Synthetic mineral fibres (SMF) is a collective term used internationally to describe fibres such as fiberglass, rockwool and ceramic fibres. The release of SMF into the air is a health risk hence the adoption of an exposure standard of 0.5f/mL (TWA), for respirable fibres according to the National Commission – Worksafe Australia. For non-respirable SMF a secondary (complementary) exposure standard of 2mg/m3 is proposed by Worksafe Australia. This proposed secondary standard is established to minimise upper respiratory tract irritation from non-respirable fibres. It does not take precedence over the respirable fibre standard. Worksafe has determined not to classify SMF as a suspected carcinogen due to the lack of supporting evidence.
