1. Product Advantages
Forever Seals Yellow UPE Spring Energized Seals stand out with exceptional performance driven by premium materials and innovative design. The ultra-high molecular polyethylene (UPE) material delivers superior wear resistance—extending the seal’s service life by 30% compared to standard sealing solutions—and excellent chemical inertness, resisting corrosion from oils, solvents, and food-grade fluids. The integrated spring-energized structure ensures consistent sealing pressure even in dynamic or fluctuating pressure environments, eliminating leakage risks. Additionally, the seals maintain flexibility and sealing integrity across a wide temperature range (-50°C to 120°C), adapting to extreme working conditions without deformation.
2. Working Principle
The seal operates on a dual-action mechanism combining UPE’s material resilience and the spring’s mechanical force. When installed in equipment grooves, the preloaded spring exerts constant radial force on the UPE sealing lip, pressing it tightly against the mating surface to form an initial seal. As system pressure increases, the fluid pressure further energizes the UPE lip, enhancing the contact force with the mating surface and reinforcing the seal—effectively preventing medium leakage. During low-pressure or static operation, the spring sustains the necessary sealing pressure, ensuring no gaps form between the seal and the surface. This dual-energization design guarantees reliable sealing performance in both static and dynamic (reciprocating or rotating) applications.
3. Product Details
Material Composition: The sealing body is made of high-purity yellow UPE (density: 0.93-0.94 g/cm³), featuring a smooth, non-porous surface that minimizes friction and reduces wear on mating components. The internal energizing spring is constructed from 316 stainless steel, offering rust resistance and high elasticity to maintain force stability over long-term use.
Structural Design: The seal adopts a “lip + spring cavity” integrated structure. The UPE lip has a precision-machined 45° contact angle, optimizing surface contact area to balance sealing efficiency and friction resistance. The spring cavity is engineered with a rounded edge to prevent spring damage during installation and ensure uniform force distribution.
Dimensional Precision: All seals undergo CNC machining, with dimensional tolerances controlled within ±0.02 mm for key parameters (e.g., outer diameter, inner diameter, lip thickness). This ensures compatibility with standard equipment grooves and avoids installation gaps that cause leakage.
Surface Treatment: The UPE surface is treated with a food-grade anti-adhesion coating (compliant with FDA standards), preventing fluid residue buildup and simplifying cleaning—ideal for food processing and pharmaceutical applications.
4. Application Range
These seals are widely used across industries requiring high-reliability sealing:
Hydraulics & Pneumatics: Suitable for hydraulic cylinders, pneumatic actuators, and valves, resisting high-pressure oil and compressed air leakage.
Semiconductor Industry: Compatible with ultra-pure fluids (e.g., deionized water, etching chemicals) in wafer processing equipment, meeting strict cleanliness requirements.
Food & Beverage Processing: FDA-compliant materials make them ideal for pumps, mixers, and filling machines, ensuring no contamination of food or beverage products.
Automotive & Heavy Machinery: Used in transmission systems and hydraulic brakes, withstanding vibration and temperature fluctuations under harsh operating conditions.
5. FAQ
Q1: What is the maximum pressure the seal can withstand?
A1: The seal maintains reliable sealing at pressures up to 30 MPa (4350 psi) for static applications and 25 MPa (3625 psi) for dynamic reciprocating applications.
Q2: Can the seal be customized for non-standard groove sizes?
A2: Yes, Forever Seals offers custom machining services based on clients’ groove dimensions (outer diameter, inner diameter, depth) and application requirements—lead time for custom orders is 5-7 working days.
Q3: Is the yellow UPE material resistant to UV radiation?
A3: The UPE material has moderate UV resistance; for outdoor or long-term UV-exposed applications, we recommend adding a UV-stabilized coating (available as an optional upgrade).
