Description
Stainless Steel PTFE Oil Seals
IKSONIC supplies stainless steel PTFE oil seals for rotary shaft applications, including air-compressor replacement enquiries. The source identifies a 304 stainless steel structure and PTFE sealing material. Different lip and dust-exclusion configurations are shown; they are not interchangeable solely because their external shapes look similar.
Specifications and Seal Types
The tables below reproduce the source-listed type distinctions. Operating figures are selection references from the source, not confirmation that every maximum can be used simultaneously. Confirm the exact size, medium, shaft condition, speed, pressure and temperature for your application before ordering.
| Type | Speed | Pressure | Design and application |
|---|---|---|---|
| A | ≤ 30 m/s | ≤ 10 bar | Standard type; optional oil-return thread designs. |
| AR | ≤ 30 m/s | ≤ 10 bar | Oil-return thread variant of Type A; direction to be confirmed. |
| AL | ≤ 30 m/s | ≤ 10 bar | Oil-return thread variant of Type A; direction to be confirmed. |
| C | ≤ 30 m/s | ≤ 10 bar | Type A with an additional dust-exclusion lip. |
| B | ≤ 18 m/s | ≤ 35 bar | Double-lip rotary seal for higher-pressure applications. |
| BR | ≤ 18 m/s | ≤ 35 bar | Oil-return thread variant of Type B; direction to be confirmed. |
| BL | ≤ 18 m/s | ≤ 35 bar | Oil-return thread variant of Type B; direction to be confirmed. |
| D | ≤ 18 m/s | ≤ 35 bar | Type B with an additional dust-exclusion element. |
| L | ≤ 30 m/s | ≤ 1.5 bar | Low-friction design for bearing protection. |
| LB | ≤ 30 m/s | ≤ 1.5 bar | Type L with an additional dust-exclusion lip. |
| LC | ≤ 8 m/s | ≤ 3.5 bar | Enhanced-flexibility design for shaft roundness and runout variation. |
| LD | ≤ 8 m/s | ≤ 3.5 bar | Type LC with an additional dust-exclusion element. |
| LA | ≤ 25 m/s | ≤ 1.5 bar | Symmetric lips for separating two different fluids, such as in centrifuges. |
| Construction | Metal material | Listed temperature range | Listed linear speed | Features and example applications |
|---|---|---|---|---|
| Single-layer | 304 stainless steel | −60°C to 260°C | ≤ 25 m/s | Single-layer seal construction. The supplier describes wear, oil and corrosion resistance. Water pumps, air compressors and other compressors. |
| Double-layer | 304 stainless steel | −60°C to 260°C | ≤ 25 m/s | Adds an oil-return feature to the single-layer construction. The supplier describes bidirectional rotation for this construction. Screw air compressors, motors, air-conditioning equipment, blowers and automation equipment. |
| Triple-layer | 304 stainless steel | −60°C to 260°C | ≤ 25 m/s | Adds a dust-exclusion lip to the double-layer construction to help limit the ingress of dust, water and contaminants, together with a threaded sealing lip. The supplier describes single-direction or bidirectional rotation. Screw air compressors and chemical-fluid or gas sealing applications; exact media compatibility requires confirmation. |
Selection notes
- The two tables describe different supplier classifications. No mapping between the single-, double- or triple-layer constructions and the individual type codes has been supplied. The construction figures do not replace the type-specific figures.
- Speed, pressure and temperature figures are separate supplier-listed values, not a guarantee that their limits can be reached simultaneously. Confirm the complete operating conditions, dimensions and selected seal configuration before ordering.
- The shared B/BR/BL description also states a PV value of 100 bar·m/s. This is not a printed inequality or a confirmed combined operating point. It has not been extended to other types.
- AR, AL, BR and BL are retained as distinct variants. The source uses unreconciled directional terminology, so shaft rotation and oil-return thread direction must be confirmed. The construction-level rotation descriptions must not be applied to individual type codes.
- Chemical and gas application examples do not establish compatibility with every medium. Confirm the exact fluid or gas, concentration, temperature and pressure for the selected construction. No independent test certification or comparative service-life claim is provided.
Dimension and Application Review
No numerical diameter or width catalogue is supplied in the product selection. Provide the shaft diameter, housing bore and seal width with units, plus the existing seal reference or drawing. Photograph markings are not treated as a verified dimensional model list.
Also specify the direction of rotation, medium, lubrication conditions and expected dust or contamination. The source’s Chinese and English descriptions assign left/right return-thread directions inconsistently, so AR, AL, BR and BL must be checked against the actual required rotation rather than selected from a translated direction alone.
Frequently Asked Questions
Does the same operating limit apply to all types?
No. Use the row for the named type. The separate single-, double- and triple-layer construction descriptions have not been mapped to the letter-coded types, so their figures must not replace the type-specific values.
Are all dimensions available?
The source uses a custom-specification entry rather than a numerical size list. Send the complete required dimensions and quantity for review; an enquiry does not establish size availability.
Can I select sealing material by color?
No. Color is only a visual characteristic. Confirm the material specification and suitability for the service medium with the selected part.
What should a wholesale enquiry include?
Provide the seal type or existing reference, dimensions with units, quantity, machine application and operating conditions. Any required documentation or special material requirement should be identified before ordering.
