Our kits are dimensional equivalents built from seals we buy in. They fit and replace the original. They are not OEM parts and carry no OEM branding.
Not finding it?
Not sure this is right?
Check it with a caliper before you buy — how to measure bore, rod and stroke covers the mistakes behind most wrong orders. Send us the numbers and a photo of the old seals and we’ll confirm the fit before you spend anything.
