TRELLEBORG o-rings are widely used seals as they are efficient and economical and can be used in a wide variety of static and dynamic applications to seal practically all liquid and gaseous media.They are available in elastomeric and other materials including (among others) EPDM, FKM and NBR, offered in sizes from 10 mm to 250 mm and suitable for use in operating conditions of -40 °C to 200 °C & 25 MPa max pressure. The o-rings are used predominantly for static sealing applications as a radial static seal, e.g. for bushings,covers,pipes,cylinders,rods or as an axial static seal, e.g. for flanges,plates,caps. Their applications include from repairs or maintenance to quality assured sealing applications in aerospace,automotive or general engineering.Compared with other sealing elements,the TRELLEBORG o-rings have a wide range of advantages:

- Simple,one-piece groove design reduces hardware and design costs

- Compact design allows smaller hardware

- Easy, failsafe installation reduces risk

- Applicable to a wide range of sealing problems: static, dynamic, single- or double-acting

- Wide compound choice for compatibility with most fluids

- Ex-stock availability of many sizes worldwide for easy maintenance and repair

TRELLEBORG offers a wide range of hydraulic scrapers and wipers in metal, elastomer as well as Turcon® Polytetrafluoroethylene (PTFE) based or Zurcon® polyurethane materials specially engineered for hydraulic cylinder applications with excellent low-friction properties providing exceptional resistance to wear. A hydraulic wiper or scraper prevents contamination of the hydraulic medium that could damage wear rings, seals and other components. They are installed in sealing configurations in hydraulic cylinders to scrape dirt, foreign particles, chips or moisture from the rod of a hydraulic cylinder as it retracts into the hydraulic system.

TRELLEBORG Turcon® and Zurcon® Excluders are Trelleborg proprietary design based double-acting hydraulic scrapers with matching o-rings or without o-rings.TRELLEBORG Turcon® Excluder® 2  double-acting o-ring energized hydraulic scrapers have two functions: a) to scrape contaminants from the retracting piston rod to prevent soiling of the system and b) to hold back the residual oil film on the extending piston rod on the medium side. The o-ring maintains the pressure while the Excluder® 2 performs the scraper function. Excellent sliding properties and stick-slip free. 

TRELLEBORG Turcon® and Zurcon® Excluders are offered in Metric or Inch versions, in different sizes either as sets with matching o-rings or without o-rings. Metric version includes sizes 10 mm to 240 mm. Operating conditions: Temperature: -35 °C to 100 °C,  Speed (max):1 m/s. Appearing prices of Turcon® and Zurcon® Excluders relate to sets of scrapers and o-rings unless otherwise specified.
