Perlast® Key Features & Benefits
Most premature seal failures come down to the material, not the process. Perlast® FFKM is engineered for conditions that defeat standard fluoroelastomers: aggressive chemicals, amines, steam and CIP/SIP cycling, and temperatures from -46°C (-51°F) to +350°C (617°F).

Extreme Temperature Capability
- Comprehensive Cold²Hot FFKM capability from -46°C (-51°F) up to +350°C (617°F).
- Reliable and consistent performance.

Available to Order Now with Short Manufacturing Lead-times
- Perlast® FFKM has very short manufacturing lead-times.
- If we have stock, components can be shipped the same day.

Alternative to Kalrez® and Chemraz® FFKM
- Perlast® mechanical seals are a quality option and deliver consistent high performance.
- Perlast® mechanical seals use high-quality ingredients, backed by ISO9001/AS9100 accreditation and full batch traceability.
- Perlast® seals have been used in place of Kalrez® and Chemraz® for many years in critical applications.
- Compliant with FDA, USP Class VI, BfR, 3A 18-03, EC1935/2004, EC2023/2006, BAM, NORSOK, TOTAL, NACE, ISO10423, ISO23936-2

Universal Chemical Resistance
- A molecular structure very similar to PTFE.
- Perlast® perfluoroelastomers are resistant to almost all chemical media.
- Perlast® food/pharma grades are resistant to steam, amines and solvents – ideal for withstanding SIP and CIP cleaning regimes.
- Other Perlast® grades are resistant to acids and hydrocarbons, designed to perform in CPI and Oil & Gas applications.
