Propane Hose Locator

Pick the hookup that matches your setup. Each diagram shows End A and End B so you can order the correct hose the first time.

Before you buy a hose 1) Confirm pressure: Tank side (high pressure) vs RV quick connect port (typically low pressure after the regulator).
2) Confirm the appliance: Many grills include a regulator at the grill. If you bypass regulators incorrectly, performance and safety issues happen.
3) Quick disconnect styles are not universal. Match the series/style, not just the thread size.
Type 1 ACME = tank handwheel POL = old style tank fitting 1-20 = 1 lb bottle thread family Flare = seals at seat, no tape NPT = pipe thread, seals on threads QD = quick disconnect

Important Confirm whether the grill already has its own regulator. Some grills are designed for high pressure input, others require regulated low pressure input.
Yes, there are tons more hookups The best way to expand this page is by grouping by where the gas is coming from: 1) Tank side (high pressure), 2) After regulator (low pressure), 3) RV high pressure accessory port, 4) RV low pressure quick connect. Each group gets 6 to 10 diagrams that all share the same rules.
