Identification 6HP/8HP - seal ring completely closed on both sides - output flange
seal ring completely closed on both sides
Over the time the OE Manufacturer supplied three different executions of this item A - a seal ring which was completely closed on both sides (available with our ref. OSL-6/8HP-OU-A) which was replaced by B - a seal ring with one side open (available with our ref. OSL-6/8HP-OU which was replaced by C - a rubber lip seal/u-ring (available with our ref. URG-6/8HP-OU)
There is a reason for these changes beyond our knowledge. So far we supplied version B (our ref. OSL-6/8HP-OU) in our kits, but will change now to C (our ref. URG-6/8HP-OU)
