Filtermart™ Liquid Filters : Pleated Paper

Filtermart General Purpose Pleated Paper Filter Construction

A few specification points determine how a given pleated paper element will actually perform once it's installed:

• Media: Resin-impregnated cellulose or glass fiber, chosen based on the fluid and the capture efficiency needed.
• Micron rating: Listed on each product page; ranges from coarse pre-filtration ratings down to finer polishing ratings.
• Flow performance: The pleated surface area supports higher flow rates at a lower pressure drop than an unpleated element of the same size.
• Gaskets and adhesives: End caps are bonded and gasketed for compatibility with the fluid and operating pressure, keeping fluid from bypassing the media unfiltered.
• Dimensions and part number: Standard outer diameter, inner diameter, and length combinations that match common industrialhousings; search by part number if you already know it.

The resin treatment applied to the cellulose also stiffens the fiber, which keeps the pleats from flexing or pinching together once the element is under steady flow. That's a small detail, but it's the difference between a filter that holds its rated capacity and one that collapses early. Browse our product pages for further details.

General Purpose Pleated Paper for Industrial Applications

You'll find general purpose pleated paper elements running in systems that handle:

• Hydraulic oils
• Lube oils
• Insulating oils
• Gear oils
• Quench oils
• Fuels
• Coolants
• Solvents
• Water and industrial process water

Most facilities end up standardizing on this filter category across several of these fluid types at once, one part protecting a hydraulic pump, another guarding a coolant loop, and another sitting as a pre-filter ahead of a finer downstream cartridge.

The right media and micron rating for a gear oil line won't necessarily be right for a fuel line, so always check the fluid compatibility listed on the specific part before ordering.

With over 1.1 million cross-references in our catalog, the fastest way to find the right element is usually to search by your current OEM part number and let the cross-reference tool pull up the matching FilterMart replacement.

If you don't have a part number on hand, filter the Pleated Paper category by micron rating and dimensions instead. Most part numbers show live pricing and can be added straight to your cart; a smaller number are listed as call or email for pricing, and a few carry a stated lead time that's noted on the product page itself, so there are no surprises after checkout.

Buying by the box also brings the per-element price down, which matters if you're replacing these on a set maintenance cycle rather than one at a time. For facilities ordering on a recurring schedule, it's also worth asking about volume pricing once you know which part numbers you'll be reordering regularly.

Select the Right General Purpose Pleated Paper Filter Element

Before you order, confirm these against your current housing and application:

• Micron rating: The particle size you need removed.
• Dimensions: Outer diameter, inner diameter, and length that fit your housing.
• Media type: Cellulose or glass fiber, based on fluid and efficiency needs.
• Gasket/end-cap configuration: Sealing style compatible with your housing and fluid.
• Flow requirements: Flow rate and pressure drop your system can tolerate.
• Fluid compatibility: Hydraulic oil, lube oil, insulating oil, gear oil, quench oil, fuel, coolant, solvent, or water.
• OEM/cross-reference number: Your existing part number, which is the quickest way to confirm an exact match.

If any of these are unclear from the housing or the old element itself, our cross-reference search will usually resolve it faster than pulling the original spec sheet.

Frequently Asked Questions

What are general purpose pleated paper filters?

Industrial liquid filters made from pleated, resin-impregnated cellulose or glass fiber media, built for economical, everyday particle removal in non-specialized fluid systems.

What fluids can they filter?

Hydraulic oils, lube oils, insulating oils, gear oils, quench oils, fuels, coolants, solvents, and water, depending on the media and micron rating you select.

What micron ratings are available?

Ratings vary by part number, from coarse pre-filtration through finer polishing grades; check the listing for the specific rating carried on that element.

How do I select the correct filter element?

Match micron rating, dimensions, media type, gasket/end-cap configuration, and fluid compatibility to your current housing, or search your existing OEM part number in the cross-reference tool for a direct match.

Can these filters be used as pre-filters?

Yes, they're commonly installed ahead of finer membrane or synthetic filters to catch larger particles first and reduce the load on the downstream element.
