NICHIASU JOINT SHEET GASKET TOMBO NO. 1120 union Nominal diameter (A): 25

[Features] ● A joint sheet made mainly of expanded graphite that can be used even under relatively high temperature conditions, and can be used for low-pressure steam. ●Contains expanded graphite, aramid fiber, and NBR rubber as main components, and has excellent sealability, steam resistance, and chemical resistance. ●Since the amount of soluble halogen is small, it can be used for stainless steel flanges. ● JIS S 3200-7:2010 conforms to the leaching test for water supply equipment.

[Applications] ●Various piping such as low-pressure steam, steam return water, cold water, hot water, and air conditioning drain.

[Specifications] - Inner diameter (mm): 39 - Outer diameter (mm): 48 - Thickness (mm): 1.5

[Specification 2] ●Operating temperature range: -200 to 260℃ ●Maintenance-free: 150℃ or less ●Maximum working pressure: Water-based fluid 2-4MPa / Oil-based fluid 1-4MPa / Gas-based fluid 1MPa Maximum pressure value depends on temperature Fluctuates JIS K 6353: 1997 rubber leaching test conformity for water supply
