RWT065 PTFE Rod Scraper Rings Eliminate Rod Scoring

October 15, 2019

At Zatkoff Seals & Packings, we take pride in our high-performing products that deliver optimal results for the long term. In line with this commitment to deliver the best sealing solutions, our scraper rings were made to outperform its traditional rod scraper ring counterparts.

Our RWT065 PTFE Rod Scraper Rings are designed to scrape excess quantities of oil from the hydraulic cylinder rods of an engine. With the ability to prevent that oil from entering the combustion chamber and burning, RWT065 scraper rings effectively eliminate the potential for rod scoring, or pitting, which significantly reduces the service life of the product. Further, the rod can effectively be cleaned because the rings maintain 100% contact.

The controlled break out friction associated with conventional MS Metal Scrapers is negligible with RWT065 Rod Scrapers. These scraper rings can also be used within a range of temperatures from -450°F to +300°F(-268°C to +149°C).

Our RWT065 products are considered directly interchangeable with the MS28776 Scraper Ring which are made of copper based alloys and were designed to absorb high impact materials such as landing gear. The product’s dimensions also comply with design standards for MS33675 and assembly may be installed in either a one-piece or two-part gland.

There are multiple material selections available for RWT065 PTFE Rod Scraper Rings, including ET000, ET009, and ET001. Contact your local Zatkoff Seals representative for assistance with material selection specific to your application.

In this edition, we’ll discuss the causes and signs of extrusion damage, as well as potential solutions and methods for prevention. Extrusion damage failures often occur in dynamic applications such as hydraulic controlled rod and piston seals. These can also occur in static applications when seals are subjected to high-pressure pulsing, especially when the gland extrusion gaps are excessive.

While O-ring designs are meant to withstand outside influences within the application environment in which they are used, failure is still possible. A combination of factors, from design to human error, can contribute to the premature failure of an O-ring.
