PTFE 304 FP Type Simmerring U-Seals For Hydraulic Cylinders
FOP
Purpose and performance:
FP is a one-way sealing ring composed of a stainless steel V-shaped (0-shaped) spring and a filled PTFE U-shaped ring. It is used for slow, medium-speed reciprocating or slow-speed rotating motion situations, including hydraulic cylinders and air cylinders. It has a variety of different shapes and structures and a wide sealing pressure range, from vacuum to zero pressure and ultra-high pressure, which can ensure reliable sealing requirements. For low viscosity media and hot melt adhesive media, the sealing effect is better good. For the pharmaceutical and food processing industries, where disinfection and harsh chemical cleaning agents are required, the cavity at the spring can be filled with silicone to prevent contaminants from entering.
Features:
1. Can be used for reciprocating and rotating motion;
2. Can adapt to most fluids and chemicals;
3. Small friction coefficient and no crawling;
4. Strong anti-corrosion ability and good dimensional stability;
5. Will not contaminate food and pharmaceutical liquids, and can withstand rapid temperature changes;
Working conditions:
Temperature range: -200~+260℃
Working speed: reciprocating motion ≤15m/s, rotating motion ≤2.5m/s.
