Sealing Solutions
Rotary and static seals built to engine and driveline drawings: crankshaft and camshaft seals, valve stem seals, transmission and axle seals, and moulded rubber gasket elements. Sizes follow the vehicle platform, not a general seal table. SES holds the range as an authorised JK Fenner distributor, covering seal families Rotary shaft, valve stem, static and moulded seals; lip materials Polyacrylate, fluoroelastomer, silicone, PTFE; case types Metal cased, rubber covered, cassette; features Hydrodynamic aids and dust lips where specified. Executions include crankshaft seals, camshaft seals, valve stem seals, transmission and axle seals, among others. It is specified most often into crankshaft front and rear main seal positions and camshaft and rocker cover sealing. Every part is genuine JK Fenner through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Sealing Solutions in the parts of a plant where this particular duty actually occurs. In practice that means crankshaft front and rear main seal positions, camshaft and rocker cover sealing, valve stems controlling oil into the port, and equally manual and automatic transmission output shafts, differential pinion and axle shaft seals, water pump and oil pump shaft sealing. What links them is the duty rather than the machine name — locations: Crank, cam, gearbox, axle, valve stem. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the JK Fenner range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Rear main seal has been leaking on a high-mileage engine — Inspect crankcase breathing before fitting the new seal. A blocked breather pressurises the crankcase and pushes oil past any seal you fit. Engine burns oil on overrun with clean plugs on load — Valve stem seals of the correct compound and interference. Hardened stem seals let oil down the guide under manifold vacuum, and that shows up only on the trailing throttle. Application uses a PTFE lip seal on the crankshaft — Fit it dry with the supplied installation sleeve. Oiling a PTFE lip before installation destroys the running-in track it needs to form and it will weep permanently. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Keep the installation sleeve and the seal together right up to the moment of fitting. Nearly every fresh seal that leaks on the first start was cut on a keyway or a splined edge during the ten seconds it went on without one.
