Industrial Hydraulic Filtration

The Baldwin Filters PT670 is a full-flow cartridge element designed for hydraulic and lubrication systems on heavy equipment. It fits Caterpillar, Komatsu, Clark and other listed machinery where a 23 micron rated filter is specified. The reinforced centertube supports the media under high differential pressure. Buyers needing a different micron rating or a spin-on canister will not find it here.

Contaminant Capture and Flow

The 23 micron rating targets fine particles that accelerate wear in pumps and valves. Full-flow design routes all fluid through the media without bypass during normal operation. Furnished gaskets and two attached end seals create a reliable seal against the housing. No pressure drop or flow capacity figures are supplied for system sizing.

Installation Hardware Included

Two end seals are attached to the cartridge so no separate seal kit is required. The reinforced centertube resists collapse during cold starts or pressure surges. The unit ships as a single replacement element; no mounting hardware, bypass valves or monitoring sensors are bundled.

Questions about this item

How do I install the PT670 cartridge and which step is often missed?

Thread the cartridge onto the mounting base until the two attached end seals seat fully, then tighten to the specified torque; the step most often missed is confirming both seals are evenly compressed before final torque.

What maintenance or replacement will the PT670 need later?

Replace the cartridge at the equipment manufacturer’s recommended service interval or when the pressure differential gauge indicates restriction; the 23 micron element and reinforced centertube are not cleanable and must be swapped as a unit.

What limit appears first on the PT670 during sustained operation?

The 23 micron media loads with contaminant, causing a rising pressure drop across the element; once the bypass valve in the filter head opens, unfiltered fluid circulates until the cartridge is changed.
