4. FAQ
Q: What is part number 4F-8824?
A: Part number 4F-8824 is an O-ring for sealing the hydraulic manifold block joints on excavators.
Q: What hydraulic assembly does part 4F-8824 suit for?
A: This 4F-8824 O-ring is applied on the connecting surfaces of multi-way manifold valve blocks.
Q: What raw material is used to manufacture this o-ring?
A: It is made of nitrile rubber, which has good compression resistance and stable oil resistance.
Q: What core sealing task does this O-ring take charge of?
A: It separates independent oil passages inside the manifold block to prevent cross-flow of hydraulic oil.
Q: Where is this O-ring commonly embedded?
A: It sits inside the closed annular grooves between stacked manifold valve plates.
Q: What performance characteristic fits manifold working conditions?
A: It maintains stable sealing under static pressure and small pulsating pressure shocks.
Q: What problem will cross oil flow bring to the machine?
A: It causes mixed oil signals and leads to uncoordinated movement of working attachments.
Q: What work should be finished before assembling the manifold?
A: Clear metal debris from the groove and check the flatness of the mating sealing surface.
Q: Is there a key installation tip for stacked manifold seals?
A: Make sure the O-ring stays fully seated in the groove before tightening the manifold bolts.
