Balanced type Metal O-Ring made of metal tube which is formed and buttwelded into various shapes having be holes at the inside against internal presure or at the outside external pressure.
It is mainly used for higher presser exceeding 70㎏f/㎠, our experimental experience shows that it withstands 6,000 atu hydraulic pressure.

Applications :
On joint in aircrafts, pile, vacuum equipments, combustion engines.
electronic apparatus, heavy electric machinery and apparatus.
Hydraulic machinery and equipment, plastics forming machines.

NOTES

When using in the fluid at pressure higher than 500㎏f/㎠ please consult with SAM SUNG INDUSTRY CO., LTD engineering staff because it is necessary to limit the dimensional tolerance of metal O-ring to less than half of ordinary case.

1. Please consult with SAM SUNG INDUSTRY CO., LTD engineering staff when using in the fluid at pressure higher than 50㎏ f/㎠ because it is necessary to limit the dimensional tolerance of metal O-ring to less than half of ordinary case.
2. The depth of plating ad PTFE coating is as described below.
Silver, nickel. copper plating 0.025~0.040mm. PTFE coating 0.025~0.050mm.
3. The tolerance of metal O-ring is generally determined on the basis of its outside diameter.
Please so specify if metal O-ring is intended for sealing fluid at pressure higher than 5㎏f/㎠ from outside.
