Plug

1. Structure
The SS top plug and DS bottom plug are designed and manufactured in compliance with SY5394-91 standards. The core, made of aluminum alloy, has great drill capability. The plug is made of imported nitride butadiene rubber and offers oil, acid-alkali resistance. Due to unique structure, the plug provides excellent scraping and displacement.
