Protect downhole chemical injection systems from fluid intrusion, plugging, corrosion, and premature component failure with the Republic Oil Tools TruCheck Defender.

When chemicals are not actively being pumped, conventional injection valves may allow wellbore fluid to migrate into the valve body and main spring cavity. Over time, this contamination can interfere with chemical delivery and reduce long-term system reliability.

Installed below the TruCheck Injection Valve, the patent-pending TruCheck Defender provides a dedicated sealing seat at the lowest point of the system. This barrier helps stop wellbore fluid before it can reach and contaminate the check valve’s main spring.
