12 DISOGRIN PIston U-CUP Seal Features & Benefits Extrusion resistant heel provides effective operation at high pressures up to 6,000 psi Knife-cut dynamic lip for maximum sealing force and superior performance Made from Disogrin 9250 urethane, our premium urethane, for its outstanding wear and tear resistance, ensuring maximum service life Asymmetrical design positions the PI securely in housing to prevent twisting, assuring low leakage performance Features & Benefits The PI Piston Seal provides superb sealing performance and very long service life. Single acting design can be used separately for single acting cylinders or in back-to-back tandems for double acting cylinders. Asymmetrical design assures the highest performance by preventing tipping and twisting in the housing. Knife-cut lips on both the dynamic and static sides assures maximum sealing force to provide maximum motion control while preventing drift. The PI Piston Seal is made from DISOGRIN 9250, world renowned for its resistance to wear and tear and for its very low compression set. The result is superior performance and longer operating life. The PI is resistant to pressure spikes and diesel effect. Capable of withstanding pressures up to 6,000 psi and 300 F (intermittent), the PI Piston Seal is excellent choice for those tough applications with high pressures or temperatures where other seals fail. No adhesion effect on sliding surface, even after a long standstill. Superior performance over a wide range of temperatures and hydraulic fluids. Page PI-2

26 VERCO M-Seals NOW Vented Too! The Simrit Group Freudenberg-NOK

27 VERCO M-Seal Features & Benefits Positive, Double Lip Sealing Surface Roll Resistant 2 Piece Design for Maximum Stability and Performance Vented for optimum sealing Features & Benefits M-Seals are designed to be a bi-directional low and high pressure seal. Because of the unique unit loading, they are a very positive, no drift seal. This type of seal design will not withstand a great amount of side loading. To increase the life of the seal dramatically, Verco Cool Blue Wear Rings should be used in conjunction with a M-Seal. This will insure centering and compensate for any side loading or misalignment. Cool Blue Wear Rings can increase seal life as much as 10 times! UNIQUE SEAL GEOMETRY: The geometry of the M-Seal allows a fluid reservoir between the two points of the M (in between the two separate sealing surfaces). This provides extra lubrication for reduced breakaway and running friction. The square or rectangular load ring provide positive, no drift sealing in many cylinder applications. RESISTS SPIRAL FAILURE: M-Seals are generally rectangular in cross section providing improved stability to resist cocking, twisting, sticking, and rolling. EASY TO INSTALL: Because of the unique 2 piece design M-Seals are a SNAP to install. No more resizing as is the case with many other types of seals. FLUID PRESSURE RANGE: VERCO M-Seals are rated to withstand pressure up to 5800 psi at recommended groove dimensions and tolerances. FLUID & TEMPERATURE RANGE: Temperature limits of -65º to +300º F can be attained with POLY-TEMP and VISTHANE II compounds. EURO-THANE and VIS-THANE have a range of -65º F to +220º F and is the standard compound. NOW VENTED: This causes the seal to be more responsive to high speed pressure shifts.

The standard seal has been designed to replace an O-ring (without back-ups). This is a 2 piece unit. Because of the rectangular cross section design, this seal is very resistant to rolling or twisting. If you are replacing an O-ring and two back-ups, we recommend that you use the appropriate 1718-xxx seals and two 1756-xxx, VERCO s patented vented back-ups. The 1718 SERIES is our most popular with medium duty cylinder applications.

The unique thing about this series is that it will interchange with existing seals already being used. As well as being a retro-fit, it is an immediate upgrade. This series will interchange with VERCO Series 1708, Dynamic Rectangular PTFE, Parker 1800 Series, and many of Disogren M-25 Series.

Unlike the others, this seal is much wider to give maximum resistance to spiral failure. The unique design of series 1716 makes this a quiet operating seal with less running friction, and much easier to install. Series 1716 will directly interchange with Grover Series 12 seals.
