Product Description
The AQ5 piston seal is specifically designed for heavy-duty applications with large diameters. It is highly recommended as a double-acting piston seal for hydraulic equipment.
Design Description:
The AQ5 piston seal features a Quard ring elastomer with limited contact points on the dynamic sealing surface, enhancing the sealing performance of the moving interface. It combines the low friction characteristics of the PTFE material and the sealing properties of the rubber elastomer, resulting in significantly reduced friction and minimized leakage.
Applications:
The AQ5 piston seal is suitable for applications with high speed, high pressure, and pressure retention requirements. It can be used as a sealing component for double-acting piston accumulators, positional control cylinders, clamping cylinders, etc. It is widely applied in equipment such as machine tools, presses, rolling mills, shoe machines, piston accumulators, and heavy-duty suspension cylinders. It is particularly recommended for heavy-load and large-diameter applications.
Technical Specification:
Pressure: 40 MPa
Speed: 2 m/s
Temperature: -30°C to +200°C (depending on the elastomeric material)
Medium: All common hydraulic oils, including bio-oils and gases.
Clearance: The maximum allowable radial clearance (emax) depends on the working pressure and functional diameter.
Materials:
Sealing ring: filled polytetrafluoroethylene (F-PTFE)
O-ring: nitrile rubber (NBR) or fluoroelastomer (FKM)
Quard ring: nitrile rubber (NBR) or fluoroelastomer (FKM)

| Sealing Component Storage Guidelines and Recommend-ed Shelf Life | |
| Storage Recommendations: | |
| Stock Control | Follow the First- In-First-Out (FIFO) princip le |
| Optimal Temp. | Seals should be kept aw ay from heat sources like direct sunlight and heat-emitting objects . The maximum storage temperature is +32°C. Low temperatures w on't cause permanent damage to the seals but can make them brittle, leading to potential breakage if mishandled. Generally , the storage temperature for seals should not go below +10°C, and they should be brought to room temperature before installation. |
| Avoid strong light | Surfaces should be shielded from direct sunlight and artificial light sources to prevent exposure to ultraviolet radiation. |
| Moisture control | Special care should be taken during storage, and the ambient humidity should not exceed 65% . Some specific polyurethane seals that are sensitive to moisture should be stored in sealed containers |
| Keep away from oxygen and ozone | Ozone and oxygen are harmful to seals . Seals should be stored in sealed containers . Any equipment that generates sparks should be kept aw ay from the storage containers . |
| Keep away from | For seals to have a longer storage life, they should be kept aw ay from contaminants . The w arehouse should be kept clean. |
| Avoid distortion | Large seals should be stored flat instead of hanging, as prolonged hanging can cause distortion. Seals should not be placed on hooks , nails , or metal plates . |
