Parker's Sure Torque manway gasket design will improve system performance, simplify assembly and lower your total system cost. Featuring an over-molded stainless steel compression limiter, The Sure Torque manway gasket comes in a number of specially engineered compounds to meet most chemical and environmental requirements. The highly efficient and rugged design of the Sure Torque manway gasket provides unparalleled value and safety. No other gasket performs as well, as long or provides the exponential system savings.

Parker's Sure Torque manway gasket has the following benefits:

• Eliminates 95% of the leading causes of Non-Accident Releases (NARs):
• Stainless-Steel Compression Control:
o Approved for impact wrenches
o No need to re-torque – resulting in less labor hours, less incidence of injury, and less time exposed to the elements
o No over-torqueing possible – preventing the potential of ruptured gaskets which results in less tank car maintenance repairs
o Impossible to drop into the tank car – no need to “fish” out gaskets
• Geometrically designed seal:
o Long life (tested up to 30 uses)
o Easy replacement/ no residue to scrape off/ no damage to nozzle

Parker offers the following FDA approved elastomers:
• EPDM (EJ590-70) – A white material that offers good temperature resistance – having a range of -65°F to 300°F. This material is the recommended material for optimal steam and water resistance and also has excellent ozone resistance. This material is acceptable for repeated use with dry food, repeated use in contact with aqueous food, repeated use in contact with fatty foods, and for use with milk or edible oils.
• Nitrile (N1069-70) – A black colored material that offers a temperature range of -30°F to 200°F. This material has excellent wear resistance – but is not as resistant to ozone as the other materials offered. This material is acceptable for repeated use with dry food, repeated use in contact with aqueous food, repeated use in contact with fatty foods, and for use with milk or edible oils.
• EPDM (E3609-70) – A black material that offers good temperature resistance – having a range of -65°F to 300°F. This material is the recommended material for optimal steam and water resistance and also has excellent ozone resistance. This material also has slightly better abrasion resistance than the white EPDM. This material is acceptable for repeated use with dry food, repeated use in contact with aqueous food, repeated use in contact with fatty foods, and for use with milk or edible oils.
