PTFE O‑Ring for Titan PowrTwin, PowrTex, PowrLiner & PowrBeast
The Titan 891-193 PTFE O‑ring is a genuine OEM replacement seal made from polytetrafluoroethylene (PTFE). It is used in fluid sections, valve assemblies, manifolds, and other high‑performance sealing applications on a wide range of PowrTwin, PowrTex, PowrLiner, and PowrBeast sprayers and pumps.
PTFE O‑rings offer exceptional chemical resistance to solvents, paints, and aggressive coatings, as well as a low coefficient of friction for dynamic sealing applications. A worn, flattened, or damaged O‑ring can cause fluid leaks, pressure loss, or contamination. Replacing with the correct PTFE O‑ring restores a reliable, chemical‑resistant seal.
What it does and when to replace it
| Chemical resistance | Withstands aggressive solvents, paints, and coatings |
|---|---|
| Low friction | Ideal for dynamic seals on moving parts |
| Wide temperature range | Performs in high‑temperature and cryogenic applications |
| Fluid leak at seal location | Visible paint or solvent seepage |
|---|---|
| Flattened or deformed O‑ring | Loss of cross‑section from compression set |
| Hardening or brittleness | PTFE can become stiff over time, losing sealing ability |
| Nicks or cuts | Physical damage during assembly or from debris |
