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

VERCO Poly-Hone Piston Seal Features & Benefits Series 1704 Square Section Series 1708 Rectangular Section Features & Benefits Poly-Hone Piston Seals are directly inter-changeable with TFE, urethane, and rubber seals now being used. O leakage at low and high PSI. Easy to install, no resizing. Superior physical properties. -65 F to +275 F Large E gaps +.020 total 0-5800 PSI Verco Poly-Hone Piston Seals are available in Series 1704 and Series 1708. The Series 1704 is a square cross section. This seal has a small footprint, making it resist hydroplaning, and is very effective at low pressures. Series 1708 is a rectangular cross section. This seal has a much larger footprint. It is designed for the more demanding application. Series 1708 is able to withstand much higher shock loads. It s rectangular shape resists rolling or twisting making it more stable in the groove. For longer life use Cool Blue Ultra-Precision Wear Rings Poly-Hone Piston Seal Double Acting 5000 PSI Seal
