Question by: Keith H on Feb 9, 2026, 4:35 PM
does this fitting work without a mandrel during installation, or do i need extra tooling for it?
Answer by: Customer Support on Feb 11, 2026, 6:38 AM
No mandrel is needed for this one. You'll use the 4599-FP416 pusher, and that's the only installation tool required. Keeps the process straightforward and cuts down on setup time when you're working through a stack of fittings.
