702230 O-Ring TS PFA

The 702230 O-RING TS PFA by Blackmer is a high-quality sealing component designed for use in positive displacement and sliding vane pumps. Manufactured from perfluoroalkoxy (PFA), a type of polytetrafluoroethylene (PTFE), this O-ring provides excellent chemical resistance, high temperature tolerance, and durability in demanding industrial applications. The O-ring has a cord diameter of approximately 2.253 mm, ensuring a secure and leak-proof seal within pump assemblies. Constructed from PFA material, the 702230 O-RING resists aggressive chemicals, including solvents, acids, and hydrocarbons, making it suitable for chemical processing, pharmaceutical, and food-grade applications. It has a Shore A hardness of about 60, contributing to its flexibility and effective sealing. The dimensions are tailored to fit specific Blackmer pump models, providing a reliable, long-lasting seal. This O-ring features a standard cross-section and compressed thickness that enable performance under pressures up to 150 psi (10.3 bar) and temperatures ranging from -20°C to +150°C (-4°F to +302°F). Its smooth, polished surface minimizes wear on mating parts, maintaining sealing integrity over time. The 702230 O-RING is compatible with various fluids, including aggressive chemicals, hydrocarbons, and process media, depending on application specifics. Ideal for maintenance, replacement, or new pump assembly, the 702230 O-RING is suitable for industries such as chemical processing, water treatment, and pharmaceuticals, where leak-proof and chemical-resistant seals are critical. It is supplied as a single unit without additional accessories. For optimal performance, it should be inspected regularly for signs of wear, cracking, or surface degradation, and replaced as needed. Proper care includes routine cleaning with compatible solvents and avoiding abrasive tools. Store the O-ring in a cool, dry environment, away from direct sunlight and ozone sources, to prolong its lifespan. Using the 702230 O-RING ensures reliable sealing performance in demanding industrial environments.
