FABCO-AIR, Inc., 3716 N.E. 49th Avenue, Gainesville, FL 32609 • www.fabco-air.com COMMON ROD GLAND CONFIGURATIONS STANDARD SEALS HYTHANE (Twin Lip): Standard for the HHD cylinders. This material exhibits most all of polyurethane's mechanical and physical properties, specifically its wear and extrusion resistance. The twin-lip is known as a lower friction seal with the same if not better seal capabilities as a loaded lip poly seal. Its temperature range is generally -49°F to +230°F (-45°C to +110°C). This type of polyurethane is generally less sensitive to humidity and water than other plain urethanes. LOADED LIP SEALS Loaded lip seal designs are pre-energized to help seal in low pressure applications. In high pressure applications the loaded seal expands even more to increase pressure on the sealing surface to ensure a bypass free seal. Loaded lip seals are an extremely durable, high compression seal design. TWIN LIP AND BUFFER Seal combination of one filled Teflon buffer ring with an elastomer expander underneath along with a filled Teflon rod wiper. This seal combination offers high durability without adding the friction of an additional lip style rod seal. This seal package is available in a wide variety of materials to suit your temperature and fluid requirements. LOW FRICTION ROD SEALS Seal combination of two filled Teflon buffer rings with elastomer expander underneath alone with a filled Teflon rod wiper. This seal combination offers low friction and higher speeds. This seal package is available in a wide variety of materials to suit your temperature and fluid requirements.
