30-degree push-on hose end in AN8 (-8), pushing straight onto socketless hose and gripping the barb without a clamp or crimped socket. AN8 suits main fuel feeds, turbocharger oil drains, breather and catch-can plumbing, and cooler lines that need more bore than an AN6 run can give. Thirty degrees is the gentlest correction available, for when a straight fitting just fouls a bracket but a 45 would swing the hose too far off line. Gravity-fed lines such as turbo drains benefit from the extra bore, since drainage depends on volume rather than pressure. Match the hose to the fluid you are running and seat it fully before pressurising the line.
