TG4 Nitrile and FKM Oil Seal for Automotive & Industrial Applications

The TG4 oil seal is a widely used radial shaft seal designed for high-
performance sealing in dynamic and static applications. Engineered to provide
reliable protection against oil leakage, dust, and contaminants, TG4 seals are
a critical component in ensuring the efficiency and longevity of machinery
across automotive, engineering, and industrial sectors.

Key Features of TG4 Oil Seals

Superior Sealing Performance

TG4 oil seals are designed with a precision-molded elastomer lip that maintains
consistent contact with the shaft surface. This design minimizes leakage while
reducing friction, ensuring smooth operation even under varying rotational
speeds and pressures.

Durable Material Construction

Typically made from high-quality Nitrile Rubber (NBR) or Fluoroelastomer (FKM),
TG4 oil seals offer excellent resistance to heat, oils, and industrial fluids.
The optional use of FKM makes them suitable for high-temperature and chemically
aggressive environments, while NBR provides cost-effective reliability for
standard hydraulic or mechanical systems.

Reinforced Shaft Protection

Many TG4 seals feature a metal casing with a spring-loaded garter ring to
maintain optimal lip tension. This ensures a tight seal even during shaft
misalignment, vibration, or high-speed rotation, protecting both the shaft and
bearing housing from premature wear.

Versatility Across Applications

TG4 oil seals are used in a variety of systems, including hydraulic pumps,
gearboxes, automotive engines, and industrial machinery. Their ability to
perform under diverse operating conditions makes them a preferred choice for
engineers and maintenance teams seeking long-term reliability.

Benefits of Using TG4 Oil Seals

Leak Prevention: Reduces maintenance costs and downtime caused by oil leakage.

Extended Equipment Life: Protects bearings and shafts from contamination and
wear.

Wide Operating Range: Suitable for moderate to high temperatures and pressures,
depending on material selection.

Ease of Installation: Standardized sizes and robust design simplify replacement
and maintenance.


The TG4 oil seal stands out as a dependable solution for sealing applications
where performance, durability, and versatility are critical. By combining
advanced elastomer materials with precise engineering, TG4 seals help maintain
machine efficiency and minimize operational disruptions. For industries ranging
from automotive to heavy machinery, TG4 oil seals remain a trusted component in
protecting valuable equipment and ensuring smooth, reliable operation.
