Parts supplied from our European supplier
A large part of our range is held by our supplier in Germany rather than on our own shelves. We order these in for you as soon as you place the order. They normally dispatch within 7–10 working days, and are then sent on by express courier like anything else. Nothing ships to you direct from Germany — it comes to our Arlesey workshop first, so you deal only with us for returns and warranty.

Corteco Rotary Shaft Seal R-23-NBR 19016634B 25x37x8mm
Corteco nitrile rubber (NBR) rotary shaft seal, part number 19016634B, in the R-23 single lip with shaft wiper configuration. Measuring 25mm inner diameter × 37mm outer diameter × 8mm width, this seal is used in gearbox and transmission applications to prevent oil leakage around rotating shafts. Corteco is a leading European seal manufacturer supplying OEM and aftermarket automotive seals.
Specifications:
- Inner diameter: 25mm
- Outer diameter: 37mm
- Width: 8mm
- Lip style: R-23 single lip with shaft wiper
- Material: Nitrile rubber (NBR)
- Brand: Corteco
What does R-23 mean on a Corteco shaft seal?
R-23 is Corteco's designation for a single primary lip seal with an additional shaft wiper (dust lip). The main lip retains the oil; the wiper prevents external contamination from reaching the main lip. This dual-function design is standard for automotive transmission shaft seals.
What is nitrile rubber (NBR) and why is it used for shaft seals?
Nitrile rubber (NBR, Buna-N) is highly resistant to petroleum-based oils, hydraulic fluids, and gear oils. It maintains its sealing properties over the temperature range typically found in automotive gearboxes (−40°C to +120°C), making it the most common material for gearbox and transmission shaft seals.
Is this a genuine Corteco part?
Yes. 19016634B is a Corteco catalogue part number. Corteco (part of the Freudenberg Group) is an OEM seal supplier to European vehicle manufacturers and supplies original-quality replacement seals for the aftermarket.
How do I fit a rotary shaft seal?
The seal should be pressed squarely into the housing bore using a seal driver or suitable tube of the same outer diameter. Lightly lubricate the seal lip with clean gearbox oil before fitting. Ensure the shaft surface is smooth and free from corrosion or scoring at the seal contact area.
