Product Description
The HRO Rod Seal has two parts. It is designed as a two-way seal for the rod. It is a PTFE seal and an O ring combined together. PTFE is a very low-friction material, and combining it with the O Ring can be used for a wide range of operations. The HRO Rod Seal works great for the high-speed sliding of hydraulic cylinders.
