Product Description
SPGW is for reciprocated hydraulic systems. Possesing excellent performance if applied at heavy load and double sealing under high pressure working conditions. Particularly suitable for long stroke, large range of fluids and high temperature circumstance . Applicable for bigger piston gap. Simple groove structure.
Standard Materials:
Sealing ring: filled with polytetrafluoroethylene (F-PTFE)
Elasticity: nitrile rubber (NBR)
Backup ring: modified polyoxymethylene (POM) or modified nylon (PA)
Features:
• Excellent sealing performance in both dynamic and static conditions
• Allows for larger extrusion gaps, reducing processing costs depending on the application
• Can be safely used in Medium with contaminants due to the larger extrusion gaps
• Low friction and no crawling phenomenon
• Simple groove design, suitable for integral pistons
• If there are special requirements (pressure, temperature, speed, special Medium, etc.), please contact our consulting service department for recommendations on suitable materials.
Technical Specification:
• Pressure: 50 MPa
• Speed: 1.5 m/s
• Temperature: -45°C to +120°C
• Medium: Mineral hydraulic oil, fire-resistant hydraulic oil, environmentally friendly hydraulic oil, water, air, and other Medium, depending on the seal material
Applications:
These seals excel in hydraulic systems and reciprocating motion applications, particularly in heavy-duty, bi-directional piston sealing scenarios under high pressure, low pressure, and high-frequency conditions. They are suitable for both long and short strokes and can accommodate larger piston clearances in situations involving a wide range of fluids and high temperatures. They are primarily used for piston sealing in heavy-duty or construction machinery, offering excellent leak control, extrusion resistance, and durability, such as in excavators and heavy hydraulic cylinders.

| 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 . |
