DESCRIPTION
This plug provides a precise seal for unused ports or cavities within hydraulic, pneumatic, or coolant systems. The SELMUL10 designation indicates a specific size or grade intended to fit a defined port, ensuring a tight, leak‑free closure even in demanding environments. Proper engagement requires clean, burr‑free holes and correct insertion depth to avoid dislodgement during vibration. The plug helps prevent contamination ingress and pressure loss, preserving system performance and reliability. When replacing, ensure compatibility with the fluid media and operating temperature range. Regular monitoring for backing out or cracking helps maintain service reliability across the fleet.
