Overview

• Freudenberg-NOK’s Patented anti-contamination seal will work in virtually any highly contaminated systems far better than other seals of this type.
• The Freudenberg-NOK Capped T-Seal assembly consists of a filled PTFE cap, and an elastomeric energizer that are protected from extrusion and contamination by our VERLON back-up rings.
• The Freudenberg-NOK Capped T-Seal is designed to handle temperature extremes, a wide variety of fluid media and larger than normal clearances—yet it requires a short axial length gland, and assembles and installs easily in the shop or in the field.
• Unlike conventional cap-type seals, Freudenberg-NOK’s Capped T-Seal virtually eliminates piston drift.
• Freudenberg-NOK’s cap is loaded both in the static mode through high energizer squeeze, and in the dynamic mode through the proportional axial-to-radial conversion of system pressure levels.
• Thus, a fully positive seal is maintained throughout the pressure range.
• Freudenberg-NOK’s substantial, uniform cap permits a high degree of evenly distributed radial load, virtually eliminating the possibility of excessive wear and premature failure found in conventional cap type seals.
• Wider clearances can be used when designing with the Capped-T Seal.
• This allows for the use of wear rings which eliminate the possibility of piston and bore damage due to metal-to-metal contact.
• When replacing single or multiple lip seals, a substantial reduction in piston length can be achieved even with the addition of wear rings.
• This reduction does not come at the expense of clearance limits or performance.
