Product Description

Parameter	Details
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).

Queeny design engineers are able to produce a seals solution for the most basic applications,to those that are extremely complicated and unique. We are able to provide you these solutions supported by life test data and years of excellent field performance.As your partner, we provide sealing solutions for centrifugal pumps,agitators and other rotating equipment, and help you consolidate your brand and market position.

Mechanical sealing adopts the principle of mechanical friction sealing, which has excellent sealing performance, which can effectively prevent leakage and protect the safety of the environment and equipment. Compared with traditional packing seals and rotary seals, the sealing effect of mechanical seals is more reliable.

 

Our products are made of high quality materials and manufacturing processes, with a long service life and low cost of use. It can effectively reduce the maintenance costs and operating costs of equipment .

 

Our mechanical seals are designed to be easy to service and replace,simply by removing the sealing components and replacing the sealing surface and sealing ring. Compared with other sealing forms, our products are more convenient to repair and replace.

 

Mechanical seal is suitable for high temperature, low temperature, high pressure, vacuum and corrosive media and other complex environment, to ensure the stable operation of the equipment.
