Product details of the custom rubber rings
Product Description
The shapes of custom rubber rings are different and can be customized. The product is quality-assured as a strict quality control system is carried in our company. Available in multitude of ravishing designs & sizes, it is highly utilitarian as well as applicable.
1. Product Advantages
Food-Safe Material: Made of 100% imported UPE (Ultra-High Molecular Weight Polyethylene), compliant with global food safety standards (e.g., FDA, EU 10/2011). No toxic substances or odors, ensuring zero contamination to filled food products.
Superior Durability: UPE’s excellent wear resistance reduces abrasion from repeated filling machine movements, extending the seal’s service life by 30% compared to ordinary food-grade seals.
Reliable Sealing Performance: The integrated spring-energized structure compensates for slight dimensional deviations of filling machine components, maintaining tight sealing even under low pressure (0.1-5 MPa) and temperature fluctuations (-20°C to 80°C).
Low Maintenance: UPE’s low friction coefficient minimizes friction with machine parts, reducing energy consumption and lowering maintenance frequency for filling equipment.
2. Working Principle
Forever Seals’ food-grade spring-energized seals combine two core components: an UPE sealing jacket and a stainless steel energizing spring. When installed in filling machines:
The energizing spring exerts constant radial force on the UPE jacket, pressing it tightly against the machine’s sealing surface to form an initial seal.
As the filling machine operates (e.g., during fluid transfer), the pressure of the food fluid further pushes the UPE jacket outward, enhancing the sealing contact and preventing leakage.
The UPE jacket’s chemical stability blocks direct contact between the spring and food fluids, ensuring hygiene while the spring maintains long-term sealing force.
3. Product Details
Material Specifications: Imported UPE (density: 0.93-0.94 g/cm³; tensile strength: ≥28 MPa); energizing spring: 304 stainless steel (corrosion-resistant, food-safe).
Size Range: Inner diameter (ID): 10 mm - 200 mm; outer diameter (OD): 15 mm - 210 mm; thickness: 3 mm - 10 mm (custom sizes available for specific filling machine models).
Surface Finish: Smooth UPE surface (Ra ≤ 0.8 μm) to avoid fluid residue and facilitate cleaning, meeting strict food hygiene requirements.
Installation Compatibility: Designed for standard filling machine seal grooves (e.g., piston pumps, rotary fillers), no need for modifications to existing equipment.
4. Application Range
Ideal for food and beverage filling equipment where hygiene and sealing reliability are critical, including:
Liquid filling: Water, juice, milk, edible oil, and alcoholic beverages.
Paste filling: Ketchup, mustard, chocolate sauce, and peanut butter.
Semi-solid filling: Yogurt, ice cream mix, and cheese spreads.
Suitable for both automatic and semi-automatic filling lines in food processing plants, beverage factories, and small-batch food production facilities.
5. FAQ
Q1: Are these seals compatible with acidic or oily food products?
A1: Yes. Imported UPE has strong resistance to weak acids (e.g., fruit juice), weak alkalis, and edible oils, so it will not degrade or leach substances when in contact with these products.
Q2: What is the recommended replacement cycle for the seals?
A2: Under normal operating conditions (8 hours/day, 5 days/week), the service life is 6-12 months. We recommend inspecting the seal for wear or deformation every 3 months to ensure optimal performance.
Q3: Can Forever Seals provide custom sizes for non-standard filling machines?
A3: Absolutely. We offer custom manufacturing based on your machine’s seal groove dimensions (ID, OD, thickness) and operating parameters (temperature, pressure). Simply share your requirements with our technical team for a tailored solution.
Q4: Do the seals meet international certification standards?
A4: Yes. All our food-grade spring-energized seals are certified by FDA (US) and EU 10/2011, ensuring compliance with global food safety regulations for export markets.
