It is interchangeable with all other API standard designed pistons.

2) Bonded Urethane Pistons
Our bonded urethane pistons dramatically extend service life in triplex pumps with ample water cooling. Harder, more dense polyurethane construction provides superior resistance to abrasive fluids providing optimum service life in harsh drilling conditions. It is interchangeable with piston with replacement rubbers
