FKM 75 Shore A O-Rings for Standard Chemical Plant Service with Custom Size Options

FKM 75 Shore A O-Rings for Standard Chemical Plant Service

FKM (fluoroelastomer) O-rings with nominal 75 Shore A hardness are offered for chemical-plant valve, pump and flange sealing requirements. Select the size and gland fit from the equipment drawing, then check the exact process fluid, concentration and temperature against the chosen compound. Include cleaning fluids and operating cycles when evaluating a replacement for chemical service.

Features

• Nominal 75 Shore A hardness for the specified chemical-service gland
• Compound compatibility checked against process and cleaning chemicals
• Continuous and transient temperature requirements reviewed separately
• Include outdoor exposure and process-fluid requirements in selection
• Specify compression-set or endurance requirements where applicable

Applications
Chemical-plant valves, pumps, flanges, dosing and injection lines requiring FKM O-rings. Confirm the equipment drawing, process chemistry and cleaning cycle; equipment-specific standards and qualification requirements should accompany the inquiry.

FAQ

Q: Why 75 Shore A for standard chemical plant service?
A: The nominal 75 Shore A grade identifies hardness. Select it together with gland squeeze, ring cross-section, pressure and compound properties to suit the specified valve, pump or flange assembly.

Q: What chemicals does FKM resist?
A: Compatibility depends on the specific FKM compound, chemical concentration and temperature. Provide the process and cleaning fluids for review; do not select solely from a broad chemical category.

Q: What temperature can it handle?
A: State continuous temperature, peak temperature and exposure duration. Confirm the selected compound’s limits for the actual chemical medium before specifying service.

Q: When would I pick 90 Shore A FKM instead?
A: Compare pressure, extrusion clearance, squeeze and installation requirements before changing hardness. A 90 Shore A substitution should follow the equipment design and compound review.

Q: Does FKM handle sour gas and amines?
A: Submit gas composition, pressure, temperature, amine chemistry and any required qualification tests. The FKM name alone does not establish suitability for sour gas or amine service.
