Step Seal for Rod

Introduction

一、Step Sealfor Rod - GSJ

1、Product structure characteristics
It consists of a PTFE seal and a rubber O-ring as a preload element.
It is a reciprocating seal that can withstand unidirectional effects of high pressure, low pressure and heavy load and alternating pressure.
