Question by: Brenda G on Nov 5, 2025, 5:50 PM
got a 5100 quick disconnect setup, is this dust cap the right one for the -10 or -12 coupling size?
Answer by: Customer Support on Nov 7, 2025, 12:17 PM
Fit comes down to the coupling size callout. This 5100 Series dust cap is made for -10 and -12 coupling sizes, and it is a female end with a UN thread style and a 0.625 end size.
Question by: Cheryl J on Apr 2, 2025, 12:43 PM
does this cap actually let you hook up while the line's still pressurized, or do you have to bleed it down first?
Answer by: Customer Support on Apr 4, 2025, 10:45 AM
Connecting under pressure is one of the main features on this cap. It handles up to 500 psi during connection, so you can mate the halves without shutting down or bleeding the system first. That's a real time saver in applications where depressurizing the line isn't practical.
