Question by: Sheila A on Nov 30, 2025, 11:47 AM

What kinda pressure can this piston cup handle?

Answer by: Customer Support on Dec 2, 2025, 7:30 AM

This cotton fabric and rubber piston cup is rated for pressures from 0 to 3000 PSI.

Question by: Frank H on Nov 9, 2025, 12:24 PM

what's the pressure rating on these cups, and are they gonna hold up in a system running pretty close to that ceiling?

Answer by: Customer Support on Nov 11, 2025, 6:59 AM

Rated for 0 to 3000 PSI, so they've got solid headroom for most standard hydraulic setups. Cotton fabric and rubber construction gives these cups good structural integrity across that pressure range, and the neoprene material helps maintain a reliable seal without breaking down under sustained load. As long as your system stays within that 3000 PSI ceiling, you're in good shape.
