A high pressure filter cap configured to withstand a high pressure differential and to minimize the deposit of residue on the filter cap threads. The body of the cap has, protruding from its lower surface, two circular flanges concentrically arranged about a central axis. The outer flange is threaded on its inner surface to engage the threads of a filter housing. The inner flange accommodates, on its outer surface, a sealing component such as an o-ring. A retainer, removably attached to the cap, holds the sealing component in place.

A hydraulic filter includes a canister extending along the longitudinal axis. A closed end cap is at one end of the canister for closing one end thereof. A removable filter element is contained within the canister and a modular one-piece input end cap is at an end of the canister. The one-piece input end cap includes a hydraulic input chamber and a hydraulic output chamber which can be positioned in any one of three mutually perpendicular directions. The one-piece input end cap also allows for sensors to be positioned in any one of three mutually perpendicular directions. In addition, the one-piece input end cap can be utilized in base-ported or top-ported configurations while also allowing for side-to-side or side-to-end configurations.

A coalescing filter element provides an integrated filter element with a three stage design with a hydrophobic or hydrophilic coalescing layer. A coalescing filter element comprises: a) At least one particulate filtration layer; b) A coalescing layer promoting coalescing of water particles, wherein the coalescing layer is downstream of the at least one particulate filtration layer relative to the flow of fluid through the element; c) An annular coalescing space downstream of the coalescing layer; d) A sump in a lower portion of the filter element in fluid communication with the annular coalescing space; and e) A hydrophobic layer downstream of the annular coalescing space, wherein fluid being cleaned by the element flows through the hydrophobic layer. The coalescing layer may be a hydrophobic or a hydrophilic coalescing layer. A filter assembly will include the coalescing filter element of the present invention.
