Product Description
High-pressure joints in lifting and industrial machinery often fail when round O-rings cannot seat correctly in rectangular grooves. The Factory High Quality NBR FKM Acm Rubber Sealing Ring Square Rectangle Rubber Ring Soft Rubber Ring addresses that gap with a rectangular profile engineered for stationary sealing. The product name indicates availability in three common elastomers — NBR (nitrile), FKM (fluoroelastomer), and ACM (polyacrylate) — while the listed specification FPM corresponds to fluoroelastomer grade, giving buyers a clear starting point for chemical and temperature compatibility discussions.
The ring is classified as a stationary seal, meaning it is intended for fixed joints rather than dynamic shafts. Its performance attribute is high pressure, which for rubber seals typically involves resisting extrusion and maintaining compression set under sustained load. Buyers can request specific colors and markings, allowing the part to be integrated into OEM assemblies with traceability or brand requirements.
Below is a feature-to-benefit mapping drawn directly from the supplier’s published data:
| Feature | Buyer Benefit |
|---|---|
| Model NO. Rubber Seal | Part identification matches standard seal nomenclature for quick sourcing. |
| Type Stationary Seal | Designed for fixed-groove applications; no dynamic wear considerations. |
| Performance High Pressure | Suitable for systems requiring resistance to high-pressure fluid or gas. |
| Shape Rectangle Ring | Fits rectangular and square grooves where round O-rings may roll or leak. |
| Standard Standard | Conforms to standard dimensions, simplifying replacement and interchangeability. |
| Color as Request | Enables color-coding for assembly line or brand identity. |
| Mark as Request | Custom marking supports traceability, lot control, or private labeling. |
| Quality High Quality | Consistent manufacturing grade for reliable sealing performance. |
| MOQ 500 | Low minimum order for pilot runs or initial stocking. |
| Production Time Based on Quantity | Lead time scales with order size, offering flexibility. |
| Transport Package Carton Box or as Request | Packaging can be tailored to shipping or warehouse needs. |
| Specification FPM | Fluoroelastomer specification aligns with FKM family for chemical resistance. |
| Trademark ST | Supplied under Santian’s registered trademark. |
| Origin China, Changzhou | Clear origin for customs documentation and sourcing audits. |
| HS Code 8484200020 | Mechanical seal tariff code simplifies import classification. |
| Production Capacity 50,000,000 piece/year | High-volume capability supports blanket orders and long-term contracts. |
In addition, buyers benefit from the following:
- Price range of US$0.10–0.20 per piece keeps unit cost predictable for volume orders.
- Package dimensions of 40×30×20 cm and 5 kg gross weight allow efficient freight planning.
- Lead time of 15 days for quantities up to 5,000 pieces; larger orders negotiated directly.
- Carton box or custom packaging helps prevent transit damage and supports automation.
Material selection guidance: NBR is commonly selected for petroleum-based oils; FKM for aggressive chemicals and elevated temperatures; ACM for improved resistance to heat and oil compared to nitrile. These are general characteristics and not a substitute for application testing. Buyers should confirm exact media compatibility with the supplier before finalizing specifications.
Applications
The Factory High Quality NBR FKM Acm Rubber Sealing Ring Square Rectangle Rubber Ring Soft Rubber Ring is listed under Manufacturing & Processing Machinery, Industrial Equipment & Components, Lifting Equipment, and Lifting Sling categories. These categories point to use in sealed joints on hoists, lifting slings, hydraulic assemblies, and general industrial machinery where a rectangular stationary seal is required. The high-pressure performance rating makes it a candidate for hydraulic cylinders, flange connections, and other static sealing points in lifting and processing equipment.
Because the ring can be ordered in NBR, FKM, or ACM, sourcing teams can select the elastomer based on the specific oil, fuel, or chemical exposure in their application. NBR is widely used for oil resistance, FKM for higher temperature and chemical resistance, and ACM for moderate heat and oil resistance. Without independent testing data from the supplier, buyers should confirm material compatibility for their media before finalizing a purchase.
Changzhou Santian Vehicle Industry Technology Co., Ltd. also lists oil, cylinder, car, and radiator among its manufactured and sold product lines. This breadth suggests that the rectangular sealing ring may serve adjacent assemblies such as oil cylinders and radiator connections, though specific fitment should be verified with the supplier.
