You found a filter that is almost right.
The size is slightly off. The slot gap isn’t ideal.
And forcing it to fit your system doesn’t feel like the right solution.
That’s usually a sign: you may need a custom filter.
5 Signs You Should Choose Custom：
If your diameter or length doesn’t match off-the-shelf options, custom is the only way to ensure proper fit.
Standard filters offer fixed gaps (0.1 mm, 0.5 mm, 1 mm…).
But real applications often need something in between.
We produce 0.02–5 mm slot gaps, based on your requirement.
Need 5, 10, or 50 pieces?
Most large factories won’t take it.
We do small batches — even 1 piece.
Not ready for bulk production?
Start with a single sample and test before scaling.
Flange, thread, clamp, or special fittings —
custom ensures it fits your system exactly, without leakage or modification.

Custom vs Standard — The Real Difference
A standard filter fits a catalog.
A custom filter fits your system.
“Almost fit” often leads to leaks, clogging, or poor performance.
Custom avoids that.
