The Titan 449-212 Plug with O-ring is a genuine Titan-manufactured replacement component designed for use on compatible PowrLiner, PowrTwin, and PowrTex equipment. This tank plug seals the fluid reservoir opening, preventing leaks, contamination, and pressure loss. The integrated O-ring provides a reliable, reusable seal that maintains integrity under operating conditions.
In line stripers and airless sprayers, the tank must remain sealed to prevent fluid from escaping and to keep debris out of the system. Over time, plugs can become cracked, threads can strip, or O-rings can compress, harden, or deteriorate due to chemical exposure. A damaged or missing tank plug can lead to fluid leaks, loss of prime, contamination of the fluid, and system inefficiency. Replacing a worn tank plug with this genuine Titan component restores a positive seal, ensures clean fluid delivery, and prevents operational interruptions.

When replacing the tank plug, these associated components are often inspected or replaced to ensure a complete repair.
Inspect tank for cracks or damage around the plug opening; replace if compromised.
Check for contamination that could indicate seal failure; clean or replace as needed.
Inspect tank cap for proper sealing and vent function; replace if damaged.
