Engineering notes

How this family is specified

Hydraulic and lube circuits fail from contamination faster than from mechanical wear. The element is the cheapest control point in the system — and the one most often bought wrong, matched on thread or housing rather than on micron rating, collapse pressure and media.

The range spans brand-compatible interchange elements, stainless steel and fiberglass media, elements located by circuit position (return line, suction, pressure line), coalescer separators for oil-water separation, and lube and process oil elements. Stainless elements in 304 and 316L are cleanable and return to service; disposable media is rated from 1 μm upward.

Media

Fiberglass for fine filtration and high dirt-holding capacity; resin paper for general duty; stainless mesh and sintered media where the element is cleaned and reused.

Rating

1, 3, 5, 10 and 20 μm grades and coarser mesh are all held. State whether the requirement is absolute or nominal — the two are not the same number.

Geometry and interface

Outer diameter, length, end-cap and seal arrangement decide whether an element fits the housing. Thread, bayonet and clamp styles are all covered.

Circuit position

Return-line elements see surge flow, suction elements see inlet vacuum, pressure-line elements see full system pressure. The same micron rating in the wrong position still fails.

Questions buyers ask about this family

Can you match an element from the part number on the old filter?

Yes, that is the normal route. Send the part number, or the element dimensions if the number has worn off. Cross-references are held for fourteen hydraulic brands, and the model page states the platform the element corresponds to.

Are these original brand elements?

No. They are independently manufactured replacement elements. Brand names appear only to describe which platform an element is compatible with; we are not affiliated with or authorised by those manufacturers.

What is the difference between absolute and nominal rating?

Absolute rating is the largest particle that passes the element under the test method stated; nominal is a statistical efficiency figure. A nominal 10 μm element is not equivalent to an absolute 10 μm element, and quoting one when the machine specifies the other is the most common source of repeat failures.

Can stainless elements be cleaned and reused?

Yes. 304 and 316L mesh and sintered elements are cleanable — backflush, ultrasonic or chemical — and return to service. We state the construction so the cleaning method can be confirmed before ordering.

Do you supply samples or small trial quantities?

Yes. Trial quantities and mixed-model consolidation are supported, which is usually the practical way to verify fit and rating before committing to a contract volume.
