Excellent wear resistance
Using these in high vibration equipment. No wear noticed after 3 months of continuous operation. Highly recommend.

Good quality brass
Material feels solid and well machined. Delivery took a bit longer than expected but the product quality makes up for it.

Accurate dimensions
Measured ID with calipers, spot on. There was a minor surface oxidation mark but it did not affect performance.

Perfect fit for lathe repair
Works great on my old lathe repair. Smooth operation and the self-lubricating feature saves time on maintenance.

Self-lubricating works
No need for oiling in hard to reach spots. Very convenient for machinery that runs intermittently.
Q: Can you cut these to custom lengths?
A: We offer standard lengths, but custom cutting is available upon request via customer service.
Q: Are these suitable for underwater applications?
A: They perform well in water, but prolonged submersion may affect lubrication efficiency over time.
Q: Can these be used with stainless steel shafts?
A: Yes, they are compatible with hardened steel and stainless steel shafts.
Q: What is the lead time for bulk orders?
A: Standard sizes ship within 2 days. Bulk orders over 500 units take 1-2 weeks.
Q: Do I need to add grease during installation?
A: No, the graphite plugs provide self-lubrication. Initial light oil is optional but not required.
