IC13

The Internal Check Fittings (IC13 Style) are robust inline fluid regulation components configured with heavy-duty UNC thread connections ranging from 3/4″-10 up to 1″-8. They feature a simplified, springless internal check check architecture utilizing high-durability AISI 52100 chrome alloy or K-Monel® sealing balls to reliably secure fluid barriers under severe system conditions.
