The REPCO Oil Seal 1.156x1.688x0.438 T2 NBR is designed for industrial rotary shaft applications requiring dependable lubricant retention within a compact inch-size housing.

Installed between a rotating shaft and stationary housing, the seal creates controlled radial contact with the shaft surface. This helps reduce leakage of oil or compatible grease while limiting the entry of dust, dirt, moisture, and abrasive contaminants into the bearing, gearbox, pump, or transmission assembly.

The product is identified by the REPCO manufacturer designation T2. Because industrial seal profile codes are manufacturer-specific, the exact sealing-lip geometry, dust-lip arrangement, outside-diameter construction, spring configuration, and installation direction should be compared with the original seal or technical drawing before replacement.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing element is generally compatible with:

• Mineral oils
• Gear oils
• Hydraulic oils
• Bearing grease
• Petroleum-based lubricants
• General industrial lubricating fluids

NBR provides good resistance to oil, wear, and abrasion under standard industrial operating conditions. Compatibility should be confirmed before use with aggressive chemicals, high continuous temperatures, ozone-rich environments, or specialized synthetic lubricants.

The inch dimensions correspond approximately to:

Shaft diameter: 1.156 inches or 29.36 mm

Housing diameter: 1.688 inches or 42.88 mm

Seal width: 0.438 inch or 11.13 mm

The specific inch dimensions suggest that this seal may be intended for a dedicated bearing housing, gearbox, pump, transmission, axle assembly, or OEM industrial machine. Accurate dimensional measurement and T2 profile verification are essential before installation.

🔁 Equivalent

Suitable replacement for compatible:

• REPCO T2 Rotary Shaft Seal
• 1.156x1.688x0.438 Oil Seal
• 29.36x42.88x11.13 Rotary Seal
• Inch-Size NBR Oil Seal
