Usage: Usually used for aluminium piston without hardening treatment, which can reduce the wear of aluminium piston caused by the rotation of ring
Feature: 1. Single straight incision design, high incision strength, not easy to break
2. Easy to install

Usage: Most widely used, but not recommended for aluminium piston without hardening treatment
Feature: 1. Inclined notch design, better sealing performance than straight notch
2. Easy to install

Usage: Suitable for medium and high voltage
Feature: 1. Pressure balanced design, effectively reduce the wear of the lower ring under high pressure
2. Easy to install

Usage: Two-lobe design, often used in small cylinder diameter
Feature: Inclined incision design, less leakage than straight incision

Usage: mostly used for small cylinder diameter, medium and high pressure gas
Feature: 1. Two-lobe design, brittle wear-resistant materials can be used in small cylinder diameter
2. Pressure balance design can reduce ring wear and prolong service life
3. Inclined incision, relatively small leakage

Usage: Used in light gas
Feature: 1. Design of lapping incision, high sealing efficiency
2. Easy to install

Usage: Used in small diameter, high pressure, light gas
Feature: lapping incision design, high sealing efficiency

Usage: For low pressure, light gas
Feature: 1. Double-ring structure, L-ring + rectangular ring design
2. Incisions staggered, high sealing efficiency
