does this fitting need any kind of sealant or mandrel when you're putting it on, or does it just go straight on the hose?
Answer by: Customer Support on Jan 17, 2026, 7:03 AM
No sealant and no mandrel required. That's actually one of the main advantages of the socketless design. You're working with a reusable brass fitting that connects directly to the -04 hose without any of that extra prep work. Makes the installation process a good bit simpler, especially out in the field where you don't always have every tool on hand.
