Frequently Asked Questions

What hose diameter does this barb fit?

This hose barb is designed for 1.0" (one inch) outside diameter tubing. Measure your existing hose before ordering to ensure proper fit.

Can I use this fitting for both water and propane systems?

Yes, this brass fitting is suitable for fresh water, gray water, black water, and propane applications. Its brass construction handles the demands of multiple RV systems.

Do I need additional clamps with this hose barb?

While the barb design creates a tight grip on hose tubing, we recommend using stainless steel hose clamps on both sides of the connection for maximum security and to prevent leaks during travel.
