Molded Rubber Sanitary Gasket

Molded Rubber Sanitary Gaskets are precision-engineered sealing components designed for hygienic pipeline systems that demand strict cleanliness, chemical resistance, and reliable leak-free performance. These gaskets are produced through high-precision molding to ensure stable dimensions, smooth sealing surfaces, and excellent compatibility with sanitary fittings such as Tri-Clamp, DIN, and ANSI flanges.

      

Manufactured from premium sanitary-grade elastomers-including Silicone, EPDM, Viton, and Buna-N (NBR)-as well as PTFE for special chemical applications, molded sanitary gaskets deliver consistent sealing for food processing systems, dairy production, beverage lines, bio-pharmaceutical plants, and clean-in-place (CIP/SIP) environments.

 

 

2.1 Precision-Molded Construction

Molded production ensures:

• Uniform thickness
• High sealing accuracy
• Tight dimensional tolerance
• No flash or burrs on sealing surfaces

This guarantees reliable sealing under both static and dynamic operating conditions.

 

2.2 Hygienic & Non-Contaminating

All materials are compliant with sanitary requirements:

• FDA food-contact grade
• Safe for pharmaceutical media
• Resistant to cleaning chemicals, steam, and common sterilization processes

Ideal for hygienic operations requiring contamination-free fluid transfer.

 

2.3 Broad Chemical & Temperature Resistance

Different material options allow compatibility with:

• Hot water & steam (EPDM / Silicone)
• Oils, fats & solvents (Viton)
• Aggressive chemicals (PTFE)

Temperature resistance ranges from –40°C to +260°C, depending on material.

 

2.4 Seamless Fit for Sanitary Standards

Compatible with:

• Tri-Clamp fittings
• 3A sanitary standards
• DIN 11851 / SMS / RJT fittings
• ANSI flange connections

Installation requires no modification and ensures tight, secure sealing.

 

 

Silicone (Platinum-cured available)

High purity, excellent for pharmaceutical and high-temperature applications.

EPDM

Outstanding steam and CIP/SIP resistance.

Viton (FKM)

Superior chemical and oil resistance.

Buna-N (NBR)

Economical choice for general food and beverage sealing.

PTFE

For aggressive chemical processes and elevated temperatures.
