1. Application and properties
With double mouth, it can prevent the intrusion of dust, dirt, gravel and metal debris, and also can scrape the oil film on the piston rod, and effectively erase the remaining oil film adhering to the surface of the piston rod from the inside..
When using PTFE rod seals, it is recommended to use this dust seal together.
The sliding surface between the two lips can retain hydraulic oil (lubricant), greatly improving the friction condition and accordingly prolonging the service life of the seal.
Small groove size and integral groove design make it easy to install.
Strong dust scraping ability
2. Standard material
NBR/FKM
