Product Description

Cylinder Cover Back Up Ring SKU: 18753A009

This Cylinder Cover Back Up Ring is a critical support element used in the cylinder cover sealing area of mud pump fluid ends. It is precision-machined from high-strength, low-friction engineered thermoplastic material such as PTFE (Teflon) or Nylon (Polyamide). The back-up ring is installed next to the primary O-ring/seal and effectively resists extrusion and damage to the softer seal material caused by high fluid pressure. It significantly increases the sealing system's pressure resistance and reliability, making it an essential component for guaranteeing long-term, leak-free pump operation in high-pressure service.
