Value Collection OS-TBH-0.750X1.250X0.250 Tb Shaft Seal

Product Description

The VALUE COLLECTION OS-TBH-0.750X1.250X0.250 is a TB-type automotive shaft seal designed to retain lubricants and exclude contaminants at rotating shaft interfaces. Constructed from Buna-N (nitrile rubber), this seal measures 0.75 inches inner diameter, 1.25 inches outer diameter, and 0.25 inches thick. Buna-N compound provides solid resistance to petroleum-based oils, greases, and common automotive fluids, making it a dependable choice for drivetrain and powertrain sealing applications. Licensed automotive technicians and drivetrain specialists install this seal during routine shaft, axle, and gearbox service procedures where a precise interference-fit seal is required.

This TB-style shaft seal is suited for light-duty automotive and small-equipment applications where shaft diameters run at 0.75 inches and bore housings are machined to 1.25 inches. The 0.25-inch cross-section fits standard shallow-housing configurations common in transmissions, transfer cases, differentials, and auxiliary drives. Its compact profile makes it appropriate for replacement work on passenger vehicles, light trucks, and small off-road or power-sport equipment requiring a reliable fluid seal at moderate shaft speeds.

Key Features

• TB-type seal profile designed for axial installation in standard bore housings
• Buna-N (nitrile) construction offers resistance to petroleum oils, ATF, and gear lubricants
• 0.75 inches ID for precise fit on 3/4-inch shafts
• 1.25 inches OD for press-fit installation into 1-1/4-inch bore housings
• 0.25 inches thickness suits shallow housing depths common in light automotive applications

Compatibility

Designed as a replacement TB-type shaft seal for automotive and light-equipment applications requiring a 0.75 inches ID by 1.25 inches OD by 0.25 inches thick nitrile seal.

Installation Notes

Installation is typically performed by an automotive or drivetrain technician. Before servicing, drain and isolate the applicable fluid reservoir and relieve any pressure in the system. Use a seal driver or press of appropriate diameter to seat the seal squarely in the housing bore without cocking or distorting the sealing lip. Avoid applying direct impact to the seal face, and inspect the mating shaft surface for scoring or wear before installation.
