Rod Seals
FOREVER SEALS' Rod Seals stand out for their use of PTFE and elastomeric composite material, which provide a low friction coefficient and high-pressure resistance of up to 50MPa. With a working temperature range of -30℃ to 100℃, these hydraulic rod seals effectively prolong the lifespan of equipment in hydraulic cylinders, pneumatic devices, and more. As a trusted rod seal supplier, we ensure our seals maintain superior sealing performance during reciprocating motion, setting them apart from the competition.

The VP Series V-Packing Set is a high-performance multi-component seal designed for heavy-duty hydraulic applications. Engineered with a combination of PEEK and PTFE materials, this seal set consists of a pressure ring, multiple V-rings, and a support ring. It provides reliable, leak-free sealing for piston rods, plungers, and pistons in demanding industrial environments.
The UN Series is a high-performance hydraulic U-cup rod seal, precision-engineered from premium polyurethane (PU) material. Designed for single-acting hydraulic cylinders, this seal provides reliable leakage prevention, excellent wear resistance, and stable sealing performance under high pressure and demanding operating conditions. Available in a wide range of standard and custom sizes.
Crafted from carbon black reinforced high-grade polyurethane, its precision U-shaped lip design ensures a tight, adaptive seal on pistons and rods during reciprocating motion—critical for leak-free performance in construction machinery, injection molders, and industrial hydraulic systems. The black formula adds superior UV resistance and anti-oxidation properties for long-term outdoor & heavy-duty use.
