QUESTION: What is the difference between carbide swivels and ceramic sealed swivels?

Answer: Example the Mosmatic 58.063 is a Carbide sealed swivel and can handle pressures up to 4000 psi. Mosmatic 38.063 Ceramic swivel can handle pressures up to 2500 psi. The higher the pressure swivel, the harder they are to make spin. If you hold in your hand and compare a 5000 psi rated swivel and compare to a 2500 psi swivel you will notice the ceramic spins easier.
