MS28775/AN6227B Series...

O-rings give effective sealing over wide ranges of pressure, temperature, and movement, with the advantage of sealing pressure in both directions and reducing friction and wear on moving parts. MS28775 O-rings meet Spec. MIL-P- 5510A and are suitable for MIL-0-5606 hydraulic fluid at 160 degrees F. Available in different internal diameters and cross-sections (widths) in inches.

MS29513 Series Rubber Fuel...

MS29513 series nitrile o-rings are resistant to fuel and are ideal for applications such as fuel injection connections and primers. They provide excellent resistance to petroleum-based products, hydraulic fluids, most silicone fluids and fuels. It is suitable for aircraft fuel uses (JP-4, JP-5). Not resistant to automotive fuels. Available in different internal diameters and cross-sections (widths) in inches.

A small amount of fuel proof grease applied to these O-rings helps the installation and operation of primers. 

M83248 Series VITON...

M83248 series flurocarbon rubber (commonly known as Viton) o-rings are  made from an advanced rubber that has extremely good fuel and heat resistance and is ideally suited for aircraft fuel system applications. These o-rings feature a high temperature resistance, excellent resistance to acids, fuels, mineral and vegetable oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, non-flammable hydraulic fluids (HFD) and many organic solvents and chemicals, low swelling in ASTM oil No. 1, and IRM 902 and IRM 903, excellent resistance to aging and ozone as well as low gas permeability and low compression set.

M83461 Series Rubber O-Ring...

M83461 series rubber o-rings are flexible, preformed o-rings specially designed for aviation use and made from a high-quality rubber-like material that flexes and expands as conditions change, filling gaps and preventing dangerous leaks. They flex slightly to fill gaps and are often used at connection points where hoses or tubing connect to a port to prevent fluid leaks. They provide a better dynamic performance than MS28775 with excellent resistance to petroleum-based products, hydraulic fluids, most silicone fluids and fuels. They can be used with MIL-H-5606 Fluid, Aircraft Hydraulic Fluid. 

CLEVELAND Grease Seal for...

A grease seal, often called an oil or dirt seal, is a type of seal utilized to retain grease in a case or housing. Grease seals close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. Preventing harmful containments from entering machinery is another critical function of a grease seal. Oil and grease seals are available in numerous lip materials. Popular materials include felt, leather, urethane, nitrile, polyacrylate, ethylene-acrylic or polyacrylic, silicone, fluoro-elastomer, tetrafluoro-ethylene propylene and PTFE. Cleveland Grease Seals are intended for use in Cleveland Wheel Assemblies. 

SKF CR SEALS Power...

CR SEALS power tranmission seals (formerly Chicago Rawhide) are included as an SKF brand  in the company's portfolio for radial and axial shaft sealing solutions in power transmission applications. CR Seals provide superior reliability and performance by retaining lubricants, excluding contaminants, and maintaining seal integrity under pressure. Both radial and axial shaft seals are offered in different series for oil and grease sealing applications. Please refer to Product Description for additional information.

TRELLEBORG O-Ring SKU:...

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 Set Turcon®...

TRELLEBORG offers a wide range of hydraulic scrapers and wipers in metal, elastomer as well as Turcon® Polytetrafluoroethylene (PTFE) based material or Zurcon® polyurethane materials specially engineered for hydraulic cylinder applications with excellent low-friction properties providing exceptional resistance to wear.

TRELLEBORG Turcon® Excluder® 2  which is a double-acting o-ring energized hydraulic scraper of Trelleborg proprietary design. It has 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. Appearing prices of Turcon® and Zurcon® Excluders relate to sets of scrapers and o-rings unless otherwise specified. Metric version includes sizes 10 mm to 240 mm. Operating conditions: Temperature: -35 °C to 100 °C,  Speed (max):1 m/s.

TRELLEBORG Hydraulic...

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 offers a wide range of hydraulic scrapers and wipers in metal, elastomer, Turcon® Polytetrafluoroethylene (PTFE) based material or Zurcon® polyurethane. These include the Turcon® Excluder®, which is the Trelleborg proprietary design of double-acting hydraulic scraper. Specially engineered for hydraulic cylinder applications, Turcon® and Zurcon® materials demonstrate excellent low-friction properties providing exceptional resistance to wear.

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. Appearing prices of Turcon® and Zurcon® Excluders relate to sets of scrapers and o-rings unless otherwise specified.
