In its uncured state, silicone rubber is a highly adhesive gel or liquid. To convert it to a solid, it must be cured, vulcanized, or catalyzed.This is normally carried out in a two-stage process at the point of manufacture into the desired shape, and then in a prolonged post-cure process.
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .
The sealant then fills all void spaces around the element and between the body. The soft sealant (a solid rubber-like component, not a liquid or paste), which surrounds the elements being sealed, and when compressed by axial force creates a hermetic seal. The continuous tension in the torqued body acts like a spring to maintain compression on ...
An end-face mechanical seal generates heat from rubbing and viscous shear and must be cooled to assure good performance and reliable operation. Typically, cooling is provided by circulating fluid around the seal. This fluid, known as a flush, may be the same as the fluid being sealed or an entirely different fluid.
Hydraulic seals can be made from a variety of materials such as polyurethane, rubber or PTFE. [2] The type of material is determined by the specific operating conditions or limits due to fluid type, pressure, fluid chemical compatibility or temperature. For instance, polyurethane seals offer good abrasion and tear resistance, while rubber seals ...
This seal will be used with a dry running containment seal and the leakage past the inner seal will be piped to a vapor recovery system. [4] The other new seal type introduced in 2nd Edition was the dry running gas seal used in Arrangement 3. This seal is designed to run on a gas barrier fluid such as nitrogen. [4]

The heart of the rotary union is the seal. The seal prevents the medium from leaking outside the rotary union while in operation. Seal types can vary from pusher-type end face mechanical seal, non-pusher type end face mechanical seal, lip seals, and o-ring seals. Most rotary unions have more than one seal. [6]
