Nine families cover what Pressure Seals actually sells. Open a line for materials, typical use, and the series inside it.
- O-RingsThe everyday seal. Stocked in standard dash sizes plus non-standard and micro-miniature. Compound choice is what usually decides the part, not the groove.Open
- Loaded Lip SealsSpring- or elastomer-loaded lips for hydraulic and pneumatic rods and pistons. The charts cover groove, cross-section, and typical pressure.Open
- Wipers & ScrapersThe part that keeps dirt, ice, and weld spatter out of the cylinder. Pair with the rod seal — a good wiper is what makes the seal last.Open
- U-CupsU-shaped lips for rods and pistons. Loaded versions hold contact at low pressure; unloaded versions suit higher pressure once the system is up.Open
- Piston SealsBidirectional piston seals, including T-seals with backup rings. Used where a single O-ring would extrude.Open
- PTFE & TeflonWhen rubber will not survive the chemical or the heat. Spring-energized, encapsulated, coated, and machined PTFE shapes.Open
- V-PackingAdjustable packing stacks for rods and stems. Still the right answer on older equipment and high-pressure static-to-slow motion.Open
- BearingsNon-metallic wear rings that keep the rod and piston off the metal. They are not seals — they keep the seals from being asked to guide.Open
- CompoundsMaterial sheets for the compounds behind the parts: NBR through FFKM, plus USP Class VI for food and medical contact.Open
