TG4 35x58x12mm NBR Brown High Pressure Oil Seal

This aftermarket TG4 high pressure oil seal measures 35mm inner diameter, 58mm outer diameter and 12mm in height, manufactured in brown NBR nitrile rubber. It features a corrugated outer diameter, triple-lip design with garter spring and an internal steel skeleton, engineered for medium-pressure rotary shaft applications.

Importers, wholesalers and MRO buyers can submit RFQ with dimension, quantity, destination and working medium for a formal quotation. Standard production Lead Time is 7–15 days.

Features & Benefits

The TG4 triple-lip design provides enhanced sealing under medium system pressure compared to standard TG seals, with a short, rigid lip profile that resists inversion.
Corrugated outer diameter resists seal rotation under vibration and accommodates thermal expansion differences between seal and housing.
Triple lip configuration: primary lip retains oil under pressure, secondary lip blocks dust and contaminants, and a third lip adds redundant sealing for heavy-duty service.
Brown NBR nitrile rubber offers good oil resistance and wear resistance, compatible with gear oils, engine oils and standard lubricants.
Internal steel skeleton with full rubber coating provides structural rigidity and reliable static sealing in the housing bore.
Standard 35x58x12mm dimensions match common TG4 housings used in transmissions, rear axles and rotary shaft applications.
This is an aftermarket replacement seal. Always verify shaft diameter, housing bore, system pressure and application before ordering.

Material & Process

• Sealing lip：NBR (nitrile butadiene rubber), brown
• Reinforcement：internal steel skeleton with full rubber coating
• Spring：carbon steel garter spring
• Pressure rating：suitable for medium pressure rotary applications; confirm system pressure with RFQ.
  Continuous working temperature: -30°C to +100°C; short-term peak up to +120°C. Confirm compound grade with RFQ for high-temperature applications.
  Compatible fluids: gear oil, engine oil, standard lubricants

Applications & Compatibility

Commonly used in transmissions, rear axles and rotary shaft applications where medium pressure and enhanced sealing are required. Application context commonly listed for this size — verify system pressure and housing type before order.
Aftermarket replacement. Verify shaft diameter, housing bore and system pressure before order.

Selection & Installation

Selection Tips

Confirm shaft ID 35mm, housing OD 58mm and seal height 12mm. Verify system pressure does not exceed the TG4 medium-pressure rating. Match NBR material to your lubricant type.

Installation Steps

1. Thoroughly clean the shaft and housing bore; remove all burrs, old seal residue, rust and contamination.
2. Lightly lubricate the sealing lips and shaft with compatible oil. Do not install dry.
3. Press the seal evenly into the housing using a proper installation tool, keeping it perfectly perpendicular to the bore.
4. Do not strike the rubber lip or hammer directly on the seal. Protect the corrugated outer surface from damage.
5. After assembly, rotate the shaft by hand to check for binding, then run under low pressure first and inspect for leakage.
