50Hydraulic PTFE rotary seals
High pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure.
High pressure rotary seals are used in pneumatic and low to medium load rotary or swing applications. The rotary piston seal is a two-piece design consisting of a standard size O-ring that powers the wear-resistant PTFE cover.
The rotary piston seal provides long-term wear and low friction without stick slip. The PTFE outer diameter has special interference with the O-ring design to eliminate the rotation between the O-ring and the seal. The inner diameter of polytetrafluoroethylene (PTFE) is designed with special grooves to provide lubrication and produce labyrinth effect to reduce leakage.

Advantages: 1. Simple groove, small dimension. 2. Good friction resistance, no creeping. 3. Good abrasion resistance, crumpling resistance, high temperature resistance. 4. With good chemical corrosion resistance, also can choose different material o-rings, it almost can work with all medium. 5. The maximum diameter of product can reach 2000mm. |

High-pressure Rotary shaft seals are one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. It is made with slip ring and o-ring/square ring.
Rotary shaft seals with PTFE ring have been specially developed for use in harsh conditions. They are used when shaft seals with classic elastomer lips reach their performance limits.
PDR rotary shaft seal extends the boundaries of elastomeric radial shaft seals, utilizing advanced materials and design techniques to provide optimal sealing performance for each application. The result is a superior sealing solution that retains a compact sealed casing.
Oil-free Air compressor PTFE piston cup seals extensively used for steam, oil, water, and other chemical applications.
BT Seal is a static seal that is used to seal rough casing and tubing. It is constructed from an elastomer with anti-extrusion spring bonded within it. Springs are available in stainless steel, elastomer could be HNBR or NBR.
SPGW is a high performance, double acting compact piston seal, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
The ID S seal is used for wellheads, downhole tools and surface pressure control equipment as a critial part.
DAS Compact Seal is a double-acting seal and guiding element comprising an elastomeric profile seal ring, two back-up rings and two guide rings.
