Titan 449-212 Plug, Tank With O-Ring for PowrLiner, PowrTwin & PowrTex

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.

Service Guidance: During routine maintenance, inspect the tank plug and O-ring for cracks, deformation, or signs of leakage. Replace if worn to maintain a proper seal.

Installation involves removing the old plug, cleaning the tank threads and sealing surface, lightly lubricating the O-ring with compatible fluid, and threading the new plug in by hand until snug. Tighten to the recommended torque, being careful not to over-tighten and damage the O-ring. Check for leaks after refilling the tank. Refer to your equipment's service manual for specific torque values.
