O-Ring Design Guide If the ID of the O-ring is stretched, the cross-section of the O-ring will decrease The following table gives the O-ring cross-sections that result from various percentages of ID stretch Compression The difference between the original O-ring cross-section and the final O-ring cross-section once installed is known as the.
reliable, reusable and long life seals in vacuum sealing applications Benefits: Leak free flanges as well as low/undetectable outgassing of the elastomeric materials can be achieved at pressure levels as low as 10 Torr by using well made O-rings in a static vacuum seal-8 environment.
A dynamic hardware surface hardness that is generally below 42 HRC will promote seal-induced polishing and wear to the mating metal surface and also inhibit the use of higher performance, wear-resistant-reinforced PTFE seal materials engineered for longer service life Hardware surfaces with hardness greater than 42 HRC generally.
Contact seals have the seal bear against its mating surface under positive pressure Clearance seals operate with positive clearance, meaning there is no rubbing contact The majority of dynamic seals are contact seals The seal is separated by a thin layer of oil film, which also serves as a lubricant.

The engineering design guide provided by Ace Seal will help you navigate the wide range of static O-ring applications used for sealing, including: flange seal, radial seal, dovetail seal, boss seal and crush seal Contact Ace Seal regarding our static O-rings engineering guide today.
The seal gets “hung up” at one point on its diameter (against the cylinder wall) and slides and rolls at the same time This twists the O-ring as the sealed device is cycled and finally causes a series of deep spiral cuts (typically at a 45 degree angle) on the surface of the seal 3.

Can impact sealing performance and life; O-Ring Gland Surface Finish Seal material must fill in voids in surface; Static surfaces - 32Ra to seal liquid -16Ra to seal gas Dynamic Surfaces: 8 to 16Ra; Too rough of a surface can result in abrasion or spiraling, even with a static seal; Lower durometer materials can be used to seal rough surface.
Dynamic O-Ring Sealing Parker O-Ring Handbook Dynamic O-Ring Sealing 51 Introduction Dynamic O-ring sealing applications are considerably more involved than static applications due to the implied motion against the O-ring seal interface Resistance to fl uids must be more carefully scrutinized than in conventional static seal designs.
Static Radial Seals: The sealing surface runs perpendicular to the seal centreline The O-Ring inner and outer diameter cross-section acts as the sealing surface Other static seals include Inflatable Seals which have hollow profiles, sealed to be air tight.
A dynamic hardware surface hardness that is generally below 42 HRC will promote seal-induced polishing and wear to the mating metal surface and also inhibit the use of higher performance, wear-resistant-reinforced PTFE seal materials engineered for longer service life Hardware surfaces with hardness greater than 42 HRC generally.
Leakage directly affects the functional behavior of a product in engineering practice, and surface topography is one of the main factors in static seal to prevent leakage This paper aims at monitoring the leakage in static sealing interface, using three-dimensional (3D) surface topography as an indicator.
seal (from the liquid-side to the air-side) to give zero net leakage 3036 Microgeometry of the Lip The texture or roughness pattern of the lip surface in the sealing region plays a major role in determining whether or not a seal will be successful If the lip surface is very smooth, with few asperities, the seal will.
A typical linear sealing system often includes static and dynamic seals, a wiper, and a bearing Assembly , Mating surfac The sealing-bearing interface, including the mating materials and.
These are sealing discs that seal threads and flange joints The discs consist of a metallic ring and a rubber sealing pad bonded together , Static Seals Surface Finishing News & Events View News & Events Fairs Films & Animations In the groove magazine News Catalogs & Brochur Newsletter Subscription Tools & Resourc.
Sealing Methods There are three primary static sealing methods in use today; the flat gasket And the molded elastomer seal The Flat Gasket is the oldest of the three Where reusability is not required and where the possibility of some leakage can be tolerated, the flat gasket may be the best choice However, this approach has several limitations.
Jul 11, 2016· This is where the percentage stretch comes in, and for a static seal, you’ll want the o-ring ID to be about 1-5% smaller than the groove ID This gives the o-ring a tight fit against the sealing surface and keeps it from moving too much with external pressure.
Designing & Producing Long-Term Static Sealing Solutions , Our unique design geometry maximizes seal-surface contact, and our precision cutting gives the customer the seal they need, with superior consistency Above all, we work closely with our customers to design the right seal for the application.

Fayed Surfaces of Similar metals - Seams and joints that possess fayed surfaces of similar metals shall be protected, at a minimum, by application of primer coating to each surface In addition to primer coating, all faying surfaces that have an exterior edge shall have the faying surfaces, seams, and edges sealed with a sealant other than primer.
Static Seals Find us on; Relevant products Clamp Seals , there is still a so-called static seal gap that must be sealed Flat Gaskets Flat Gaskets provide the static sealing of two sealing surfac Gaskets Gaskets produced by Freudenberg Sealing Technologies are designed as an.
O-ring gland design information Please contact the local ERIKS repre-sentative if an application does not clearly fall into these design parameters Static Applications There are five types of static O-ring applications: • Flange seal • Radial seal • Dovetail seal • Boss seal • Crush seal Flange Seal (Axial Seal).
