Piston Cup 3.00 Inch Supergold Flat Back
This is a 3.00 inch SuperGold piston cup in a flat back style, the flexible sealing element fitted to the piston in the fluid end of a reciprocating pump. As the piston reciprocates it maintains the seal against the cylinder liner bore, making it a routine wear part. It is sized for the FMC Bean M1324 pump.
What it is
