Pan plug seals can be made according to AS568A standard O-ring grooves (such as radial shaft seals, piston seals, axial face seals, etc.). The pan-plug seal completely replaces the general-purpose O-ring. Because there is no problem of swelling, it can maintain good sealing performance for a long time. For example, for mechanical shaft seals used in high-temperature corrosive environments in petrochemical processes, the most common causes of leakage are the uneven wear of the sliding ring, and the deterioration of the O-ring is also the main cause. Problems such as swelling, surface roughening and wear, thus greatly improving the service life of the mechanical shaft seal.

June 17, 2022The main production materials of pan plug seals
Teflon (PTFE) is a sealing material with better chemical resistance than perfluoroelastomer and good heat resistance. It can be used in most chemical fluids, solvents, as well as hydraulic oil and lubricating oil. Its swelling is very small, so it can exert its sealing performance for a long time. Various special springs are used to overcome the elasticity problem of Teflon or other high-performance rubber and plastics, and most of the Seals that can be used in static or dynamic applications are developed. The temperature range of the Pan Plug Seal can be from refrigerant to 300℃, and the pressure can be from vacuum to ultra-high pressure of 700kg. The moving speed is up to 20m/s, and the spring can be made of stainless steel, Elgiloy Hastelloy, etc. Therefore, it can be used in various high temperature corrosive fluid occasions.

In addition to the above-mentioned sealing applications in high temperature and corrosive environments, it has low friction coefficient of sealing lip, stable sealing contact pressure, high pressure resistance and large radial deflection. Therefore, it is very suitable for sealing parts of air-hydraulic cylinders, replacing U-shaped or V-shaped tightening to obtain excellent sealing performance and service life.
