LONGWELL brand replaceable rubber pistons are composed of High-quality molded nitrile rubber inserts and High-quality piston hubs.
Just like our urethane bonded pistons, we complete every step of the manufacturing process for both hub and piston rubber in-house.
Our forged steel hubs are machined at our API 7-K and ISO 9001 certifed factory, and the rubber inserts are formed and pressed.
Our replaceable rubber pistons and inserts are based off of the industry standard “Mission-Supreme” style; our inserts will ft all competitors’ piston hubs that are interchangeable with the OEM.
Piston assembly is used as a type of mud pump fluid end accessories in the oil drilling industry.
The main body of the piston assembly is made of forged steel 45# or 40Cr, and the piston cup and rubber are of high polymer materials.
In order to accommodate every drilling need in various oil fields, we at Rundong have developed superior piston assembly for customers. Our piston assembly offers the advantages of reliable performance, strong wear and hydrolysis resistance under high temperature and high pressure.

Made up of a replaceable Nitrile, HNBR Rubber this Fabric Heel piston is the most cost effective. As long as the piston hub is not worn to indicator marking the rubber can be replaced and used on the existing hub until it becomes too worn.
This was designed to provide maximum sealability for high pressure well service pumps. The proprietary material was developed to eliminate extrusion and provide excellent abrasion resistance for fracturing, acidizing, and cementing pumps.
