Specification of Gland Packing Tombo 2930 Roll
■Construction
TOMBO No.2930 features an expanded graphite (Graseal) core
covered with braided stainless steel, and treated with lubricants,
graphite, and anti-corrosion materials. This adapter packing is
well suited to high temperature and high pressure valves.
■Features
1. 100% asbestos-free.
2. Superior sealing performance compared to asbestos products
when used with a Graseal packing.
3. Little differences in performance from cryogenic to high
temperatures.
4. Expanded graphite (Graseal) has chemical resistance
properties second only to PTFE, and can be used with almost
any fluid (with the exception of those listed on page 6).
5. Less weight loss at high temperatures than asbestos packings,
with little stress relaxation.
Max.Temperature －240～400℃ (oxidizing atmosphere, in air)
－240～600℃ (non-oxidizing atmosphere)
Max. Pressure 43MPa (when used with a TOMBO No.2205-P or other Graseal packing)
