In environments where oxygen, ozone, and sunlight cause standard rubbers to crack, Carlock Sealing’s EPDM stands as the ultimate shield. Unlike NBR, which focuses on oil resistance, our EPDM is engineered specifically for polar substances. If your application involves high-pressure steam, industrial cleaning chemicals, or long-term outdoor exposure, our precision-machined EPDM provides the chemical stability to prevent premature seal failure.
Important Application Note: Carlock Sealing's EPDM is a non-oil resistant material. It is strictly not compatible with petroleum-based products.
FAQ:
Q: Why did my EPDM seal expand and turn soft suddenly?
A: This is almost always caused by contact with petroleum-based lubricants or oils. Carlock Sealing advises checking your system's fluid—if mineral oil is present, EPDM is the wrong material. Contact us for a switch to NBR or FKM.
Q: Is EPDM suitable for dynamic steam valves?
A: Yes. While PTFE is more chemically inert, Carlock Sealing’s EPDM is an elastomer, providing the necessary "spring-back" to ensure a tight seal in valves where some flexibility is required during thermal cycles.
