ORING & CORD CV.JAVATECH-SEAL Terlengkap

O - r i n g A p p l i c a t i o n s The O-ring is one of the most popular seal choices because: 1. The O-ring is cost effective in purchase price and the cost to machine the seal groove is relatively low. 2.As a bi-directional squeeze seal, the O-ring can be used in an extremely wide variety of successful applications, both static and dynamic. 3.The O-ring material allows for maximum stretch or compression and is therefore quite easy to install, generally requiring no special tools. Applications: Static: There are four varieties of static applications as noted below: 1. Axial The O-ring cross section is squeezed axially in the groove similar to a flat gasket. 2. Radial The O-ring cross section is squeezed radially in the groove between the inside (ID) and outside (OD). 3. Dovetail The O-ring is also axially squeezed in a dovetail groove. The groove design allows the O-ring to be retained in the face seal during assembly and maintenance. This is beneficial for special applications where the O-ring has to be fixed by the groove e.g. a lid which opens regularly. 4. Boss Seals The O-ring is used for sealing straight thread tube fittings in a boss. A boss is a cylindrical projection on a casting or forging. The end of that projection is machined to provide a flat, smooth surface for sealing. Straight threads used with an O-ring provide a better seal than tapered threads used alone.
