Great value for industrial grade

Comparable quality to the original manufacturer parts but at a better price point. Will definitely order again for our maintenance stock.

Exact specification match

Hard to find the specific 42/48mm sizing with 65A hardness locally. This matched the OEM specs perfectly. The spider buffer pad seated smoothly without forcing it.

Perfect fit for our pumps

Ordered these for a batch of industrial pumps. The dimensions are spot on for the GR38 coupling, and the purple color confirms the 65A hardness we needed. Vibration damping is excellent.

Solid performance

Replaced an worn-out element on a compressor. The machine runs much quieter now. The material seems resistant to oil and grease as advertised.

Good quality material

The BASF TPU material feels very durable. Installation was straightforward. Only giving 4 stars because shipping took a day longer than expected, but the product itself is top-notch.

Reliable replacement part

We use these regularly in our facility. They hold up well under continuous operation and high torque loads. No signs of wear after three months of heavy use.

5 FAQ

Q: Is this compatible with a ROTEX GS38 coupling?

A: This element is specifically designed for the GR38 series. While GS and GR series are similar, we recommend verifying your specific hub dimensions before purchasing to ensure a perfect fit.

Q: What is the maximum operating temperature for this purple spider?

A: The 65A TPU material typically operates safely between -30°C and +90°C. For applications exceeding 90°C, please contact us for high-temperature alternatives.

Q: How do I confirm the hardness is actually 65A?

A: The purple color is the industry-standard indicator for 65A hardness in ROTEX style elements. Additionally, our product description guarantees the use of certified BASF TPU material meeting this specification.

Q: Does this come as a single unit or a pack?

A: The price listed is for a single elastic element (one spider buffer pad). If you need bulk quantities for multiple couplings, please select the appropriate quantity at checkout.

Q: Is this material resistant to hydraulic oil?

A: Yes, the BASF TPU material used in this 65A purple element offers good resistance to mineral oils, greases, and many solvents commonly found in industrial environments.
