Hose Plug FAQ
Why cap an unused manifold outlet instead of just leaving it closed off with the valve?
A plug provides a more secure, leak-proof seal than relying on a valve alone, especially over time as valves wear. It's cheap insurance against a slow gas leak you might not notice until pressure or pour quality drops.
Do I need different plugs for beer line vs. gas line?
Match the plug to the fitting type and size you're capping — a barb plug for beer line barbs, a gas port cap for regulator or distributor outlets. They're not universal, so check the connection type before ordering.
