Information
Differential output shaft seal. 48 x 68 x 10 mm.
OE Match differential output shaft seal, engineered to replicate the original Porsche component that seals the output shaft on the differential housing. It prevents gear oil from leaking out where the drive axles exit the differential - a critical sealing function in the drivetrain system.
Sold each.
Fits:
Porsche 911 Carrera 3.2L 1984 - 1989
Porsche 911 Turbo 3.3 1978 - 1989
Porsche 964 1989 - 1994
Porsche 993 1995 - 1998
Porsche 996 1998 - 2005
Porsche 986 Boxster 3.2L 2000 - 2004
Porsche 986 968CS 1993 - 1995
Diagram ref no 20
The differential output shaft seal creates a pressure-resistant, low-friction barrier around the rotating driveshaft or axle stub where it exits the differential. It prevents differential oil from escaping the gearbox while allowing rotational movement, helping maintain optimal lubrication of internal gears, bearings, and limited-slip components.
Function: Installed in the differential carrier housing at the output flange, the seal’s elastomer lip bears against the rotating shaft surface, maintaining contact under variable engine speed, gear torque, and temperature conditions. The internal garter spring ensures the lip is held in consistent contact with the shaft surface, helping prevent weeping or drips that can lead to low lubricant levels and accelerated drivetrain wear.
A worn or hard differential output seal can lose its effectiveness over time, leading to leaks, oil drips, and reduced gear oil levels in the differential. Low lubricant can accelerate wear of differential bearings, gears, and limited-slip clutches - ultimately causing expensive internal damage. Replacing the seal with an OE Match component helps preserve proper differential lubrication, reduces contamination of nearby brake and suspension parts with oil, and maintains drivetrain longevity and performance.
When to replace:
• Visible gear oil leakage from the differential area
• Oil accumulating near the rear of the gearbox or under the car
• During differential service or rebuild
• After replacing output shafts/axle flanges
• Preventive maintenance on high-mile vehicles

About Gasket Sets / Gaskets / Seals / Lock Nuts
OEMatch Gasket Sets / Gaskets / Seals / Lock Nuts — Fit, Function, Confidence
For Porsche models, OEMatch supplies gasket sets, seals and lock nuts intended to protect gearboxes and differentials from lubricant loss and contamination while preserving correct internal clearances and pressure. These items are useful for routine service, gearbox rebuilds and resolving persistent transmission leaks.
Available Types
- Complete gearbox and differential gasket sets for rebuilds
- Individual shaft seals, O-rings and grommets
- Lock nuts and transmission fastener kits
Understanding OEMatch Gasket Sets / Gaskets / Seals / Lock Nuts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original gasket sets, gaskets, seals and lock nuts.
OE (Original Equipment) refers to parts matching original specifications for the gasket sets, gaskets, seals and lock nuts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM gasket sets, gaskets, seals and lock nuts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Gaskets and seals create pressure-tight joints between mating gearbox surfaces and around rotating shafts; lock nuts and fastening kits secure components subject to high torque and vibration. Correct material selection and surface condition are essential to maintain sealing performance, particularly where high temperature and exposure to transmission fluids can accelerate degradation. OEMatch integrates a broad catalogue of Porsche part references to help match application requirements.
Benefits Include
- Restores reliable oil containment to prevent leaks
- Preserves gearbox pressure and lubrication pathways
- Reduces the risk of internal wear and noise from fluid loss
Why Gasket Sets / Gaskets / Seals / Lock Nuts Wear and Fail
- Thermal cycling causing shrinkage, cracking or compression set of gasket materials
- Chemical attack or hardening of seals from aged or contaminated fluids
- Damaged or corroded mating surfaces created during service or by debris
- Incorrect installation or re-use of old sealing materials and fasteners
The Importance of Replacing with OEMatch Gasket Sets / Gaskets / Seals / Lock Nuts
Replacing worn or damaged sealing components prevents lubricant loss, contamination and consequential gearbox damage. Renewing gaskets, seals and lock nuts during a rebuild or major service restores designed sealing points and fastener security, helping to maintain smooth, reliable transmission operation and reducing the likelihood of repeat repairs.
Advantages
- Materials chosen for compatibility with transmission fluids and operating temperatures
- Restores intended sealing clearances and assembly torque behaviour
- Facilitates thorough gearbox servicing and long-term reliability when fitted correctly
