TG4 45x65x7mm NBR Blue Pressure Resistant Oil Seal

This aftermarket TG4 pressure resistant oil seal measures 45mm inner diameter, 65mm outer diameter and 7mm in height, manufactured in blue NBR nitrile rubber. It features a corrugated outer diameter, triple-lip design with garter spring and an internal steel skeleton.

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 with short, rigid lip profile resists inversion under medium system pressure compared to standard double-lip seals.
Corrugated outer diameter resists seal rotation under vibration and accommodates thermal expansion 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.
Blue 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 45x65x7mm dimensions match common TG4 housings used across engines, transmissions, rear axles and industrial equipment.
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), blue
• 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 engines, transmissions, rear axles, water pumps and industrial rotary shaft equipment 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 45mm, housing OD 65mm and seal height 7mm. 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.
