Revolutionary railcar manway gaskets
Manufactured from 100% pure PTFE utilizing our Gylon process. The 3545 Tuff-Rail gasket is specifically designed to help address those difficult installation and sealing requirements of manways. Formulated to compress and conform, the 3545 Tuff-Rail is easily installed, with excellent load retention, maintaining a tight seal even during heavy vibration and thermal cycling. The patent pending technology incorporates raised ribs to ensure the gasket performance under the limited bolt load and the narrow seating surface of the nozzle.
VALUES & BENEFITS
» Manufactured with 100% pure PTFE for universal chemical resistance
» Proprietary GYLON® 3545 and raised sealing ribs offer excellent creep resistance and long term bolt load retention
» Highly compressible for low load sealing on less than ideal sealing surfaces
» Tough, reliable and reusable—ideal for heavy vibration, thermal cycling, and overtorquing
» Engineered to a single size to fit the most common manways simplifying inventory (AAR-1, UTC-1, TRN-1)
» Unlimited shelf life and high crush resistance - issues commonly associated with rubber gaskets
MANWAY LEAK TESTING - TORQUE REQUIRED TO PASS 49 CFR 180.605 PNEUMATIC NOTE:
» Testing indicates effective range of bolt torque that passes 49 CFR visible leak test
» Garlock TUFF-RAIL® operates successfully over a wider range of loading conditions and chemicals (see graph below)
» Garlock TUFF-RAIL® can pass leak testing at ~50% less load than similar glass filled PTFE gasket
» Successfully tested for reusability » [8] Bolt AAR-1 Manway » Using A307, 7/8” bolts » Big Blue Leak Detection Fluid
» 30 psig Visible Leak Test
