PRODUCT INFORMATION
Product Details
1.98" Vault Oil Bath Protector with O-Ring
Part Numbers: 07502 + 32742
Stainless steel 1.98" oil bath protector with matching O-ring for Trailer Buddy axles equipped with The Vault HLS lubrication system. Fits standard 1.980" hub bores and helps maintain a clean, sealed hybrid lubrication chamber.
R&P Knowledge Hub
This protector is intended for Trailer Buddy hubs using The Vault HLS (Hybrid Lubrication System), not a traditional serviceable oil-bath setup.
Always verify the hub bore before ordering. This cap is built for a 1.980" bore, commonly found on many 5-lug trailer hubs using Vault-style lubrication components.
Pro Insight: Replacing both the protector and the matched O-ring together helps maintain a more reliable seal and reduces the chance of contamination at the hub opening.
R&P Service Insight
These protectors are commonly replaced when the seal surface becomes worn, the cap is damaged during removal, or the O-ring has flattened from age and heat cycling.
- Wear: Repeated hub service can affect sealing surfaces over time
- Exposure: Moisture and road debris can compromise the sealing area
- Maintenance: A fresh O-ring helps restore proper cap-to-hub sealing
