PTFE guide and wear strip

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.

Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.

Spring energized PTFE seals consist of variety of jacket profiles and spring types. It can achieve the sealing effect compensation under different pressure conditions by spring energizer.

The bonded seal is used in work-over and sand control operations. With the bonding of elastomer to a steel core, this serve to prevent excessive rubber compression under loading.

Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.

Oil-free Air compressor PTFE piston cup seals extensively used for steam, oil, water, and other chemical applications.

KZT is used in combination with anti-wear and piston ring to prevent cylinder oil from mixing with foreign particles, avoiding seal damage.

JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be  PEEK, modified PTFE.
