BRT Teflon wear-resistant ring rod seal high-quality PTFE customized brown standard size conventional or customized

Short Description:

The retaining ring does not have a sealing function, and the use of retaining rings prevents the O-ring from being squeezed into the installation clearance on the low pressure side, thereby maintaining the sealing function of the O-ring The retaining ring has no sealing function, and its function is to protect and prevent the extrusion of the seal. The retaining ring is often installed in the groove with the elastic seal ring. It is specially suitable for use with the O-ring and the star ring. Because the retaining ring is tightly installed in the groove, the retaining ring can prevent the elastic seal ring from being squeezed into the gap after compression. The retaining ring generally has a rectangular section, especially in line with the corresponding O-ring, star ring groove size.

Installation requirements

1. The installation of w and position can not be arbitrary, if not special requirements, generally need to be installed on the side of the preload, and face the direction of pressure.

2. In order to ensure the sealing performance, the cylinder block and piston rod should be pushed into the chamfer should meet the requirements.

3. The burr, chamfering and chamfering of the product should be removed to ensure the smoothness of the product surface.

4. Thread, guide ring grooves and other parts should need to have something to cover, to avoid being pushed through the grooves, holes and rough surfaces.

5 PTFE retaining ring surface adhesion dust, debris and in the process of handling and transportation adhesion of external particles to remove, pay attention to not take sharp tools to clean the surface, so as not to cause damage.

6. Avoid using tools with sharp edges during installation.

7. When the lip of the PTFE retaining ring needs to pass through the oil pressure hole, the plastic rod can be used to gently push the lip, so as to avoid the chamfering of the oil pressure hole to break the retaining ring.
