FAQ
Q: What's the difference between MPT and HB connections?
A: MPT (Male Pipe Thread) screws into female-threaded ports on tanks or fittings. HB (Hose Barb) slides over tubing and is secured with a hose clamp. This adapter bridges both connection types.
Q: Can I use this adapter for freshwater, greywater, and blackwater?
A: Yes. PVC is compatible with all three systems in RV applications. Confirm your tank model accepts this adapter size before ordering.
Q: How do I know if I need a 2" adapter versus another size?
A: Check your existing tank connection or the Dometic parts diagram for your model. The 2" size refers to the diameter of both the thread and barb—measure your current fitting or consult your RV manual.
