Product Questions & Answers

what exactly are piston packing rings used for in a hydraulic setup?
Question by: Lee P on Dec 21, 2025, 6:24 AM
Piston packing rings seal the piston inside a hydraulic cylinder, keeping fluid from bypassing the piston as pressure builds. Without a good seal there, you lose force and the cylinder won't extend or hold load the way it should. The T420 designation on these LOMAR rings refers to the specific packing style, which is built to maintain that seal under the pressure cycles a working hydraulic system puts it through.

Piston packing rings are used as sealing elements on a piston, and this part is identified as LOMAR T420 piston packing rings. They are meant for piston sealing applications where that specific T420 packing ring style is required.
