Title: Reg core delrin seal
Post by: angrybear on May 21, 2026, 12:59:20 PM
Just found a spare reg core that has no white delrin to seal against the push pin, It had just been screwed in super tight  :o  :o 
So just wondering is it a special spec (if so what) or only white to be visible ??

White delrin is used because it's harder than black.
PEEK is harder, I'd guess RAW use it because it stands up better to higher reg pressures and 250 bar fills
