Model | QT Encapsulated o - ring |
Seal Type | Encapsulated o - ring seal |
Material | Inner o - ring: Commonly Nitrile Butadiene Rubber (NBR), Fluoroelastomer (FKM), or Ethylene Propylene Diene Monomer (EPDM) depending on application requirements. Encapsulation: Usually made of thermoplastic materials like Polyamide (PA) or Polypropylene (PP) for mechanical protection and better sealing performance. |
Size | Inner diameter: Ranges from 10mm to 200mm or more depending on the application. Outer diameter: Varies according to the inner diameter and the thickness of the encapsulation layer. Cross - sectional diameter of the o - ring: Typically 2mm to 10mm, with common sizes like 3.5mm, 5mm, etc. |
Maximum Working Pressure | For NBR - based o - rings with encapsulation: Around 10 - 15 MPa. For FKM - based o - rings with encapsulation: Can reach up to 20 - 25 MPa. For EPDM - based o - rings with encapsulation: Generally around 8 - 12 MPa. |
Minimum Working Pressure | Close to 0 MPa, but the seal needs a certain pressure to ensure proper sealing contact. |
Maximum Working Temperature | NBR: - 40°C to 120°C with encapsulation protection. FKM: - 20°C to 200°C. EPDM: - 50°C to 150°C. |
Minimum Working Temperature | NBR: - 40°C. FKM: - 20°C. EPDM: - 50°C. |
Fluid Compatibility | NBR: Compatible with mineral oils, some hydraulic fluids, and water - based fluids. FKM: Resistant to a wide range of chemicals, hydrocarbons, and high - temperature fluids. EPDM: Suitable for water, steam, and some non - oil - based fluids. |
Sealing Mechanism | The o - ring provides the main sealing function by deforming under pressure to fill the gap between mating surfaces. The encapsulation protects the o - ring from mechanical damage, abrasion, and chemical attack, and also helps to maintain the shape and position of the o - ring during operation. |
Installation Method | Requires proper alignment with the sealing groove. The encapsulation may need to be carefully inserted into the groove without damaging the o - ring or the encapsulation itself. Torque values for any mating components should be followed to ensure proper compression of the o - ring. |
Maintenance | Periodic inspection for signs of wear, damage to the encapsulation, or leakage. Replacement may be required if the o - ring shows signs of degradation (such as hardening, cracking) or if the encapsulation is damaged. Maintenance intervals can range from several months to a few years depending on the operating conditions. |
Application Areas | Widely used in industrial equipment such as pumps, valves, and pipelines where a reliable seal is required. Also applied in automotive components like engines, transmissions, and hydraulic systems. In some cases, used in food and pharmaceutical processing equipment where cleanliness and chemical resistance are important. |
Testing Standards | Complies with relevant industry standards such as ISO 3601 for o - ring dimensions and performance, and other specific standards depending on the application industry (e.g., automotive industry standards for automotive applications). |
