Type MB1 is Inherently balanced metal bellow seal. This seals are independent of direction of rotation.
The unique feature of this type of seal is that, there is no dynamic 'O' rings and therefore it will never hang up or damage the shaft and sleeve, it also has an ability to handle corrosive as well as abrasive & viscous media.
These seals have self-cleaning & non-clogging construction. With selection of special bellow material it can be used in highly corrosive media.
Applications :
Generally used for handling highly corrosive chemicals, high Temperature applications, petroleum refinery etc.

General Information
HTMS Metal- C-Ring seals are made from high temperature alloy strip. The strip is cut to the required length and tig welded. The C-shape is then formed in a tool or is roll formed for bigger sizes. HTMS Metal C Rings are a logical development over our popular Metal O Ring. Metal C Rings have a better spring back then same size Metal O Rings. The seating load or the required bolting force is lower than for similar sized Metal O Rings. HTMS Metal C Rings will compensate greater flange rotation and maintain positive sealing load, better than Metal O Rings.
For sealing thin gas or low viscosity fluids, HTMS recommend to soft plate the bare metal seal with such materials as silver, gold or tin. Also PTFE as a coating is available.
For extreme low leakage requirements at elevated temperatures HTMS also produces spring energized metal C Rings. This “CS” design is basically a metal C Ring with an inserted high tensile spring.
Metal C Ring availability
- From 6 mm to +3000 mm diameter
- Cross section from 0, 89 mm to 12, 7 mm

Metal-O-rings and C-rings for extreme operating conditions
From ultrahigh vacuum up to 6800 bar (100000 psi) pressure and temperatures from -269°C cryogenic up to +980°C (-425°F up to 1800°F).
Resistant to chemicals to a large extent.
GFD metal O-rings have been developed as a secure sealing of gases and liquids. They even can be used in case of extreme conditions. These static and metallic sealing elements can be applied in ranges of ultrahigh vacuum and up to a pressure of 6800 bar. They are suitable in case of continous temperatures from 269 degrees centigrade below zero up to 980 degrees centigrade above zero and resistant to radioactive radiation, chlorides, corrosion and other aggressive influences. They neither age in use or during storage.
Advantages:
With conventional flanged joints many technical data, from which only very few are precisely available during the design state, have to be known for the calculation. Also the values for the rigidity of the flange, the screws etc. have to be available. The consequence are extensive calculations with imprecise or assumed values and the involved disadvantages. There is always a defined initial tension, no setting and smaller flange and screw dimensions with the GFD metal-O-rings or lip seals. The proof has not to be furnished with complicated and difficult calculations about unknown quantities but simply by adding the forces of pressure to the operating pressures.

General Information
HTMS Metal- O-Ring seals are made from high precision metal tube. Contrary to flat gaskets, HTMS Metal-O- Rings require extreme low bolting load. Because they feature a certain resiliency or spring back, HTMS Metal O Rings will compensate minor flange rotation and maintain positive sealing load to the sealing surface.
For sealing thin gas or low viscosity fluids, HTMS recommend to soft plate the bare metal seal with such materials as silver, gold or tin. Also PTFE as a coating is available.
HTMS Metal O Rings are made for internal or external pressure. For high pressure application HTMS advises vented or system pressure assisted Metal O Rings.
For extreme low leakage requirements at elevated temperatures HTMS also produces spring energized metal O Rings. This “OS” design is basically a metal O Ring with an inserted high tensile spring.
Metal O Ring availability
- From 6 mm to +3000 mm diameter
- Cross section from 0, 89 mm to 12, 7 mm
- In house plating, Silver, Gold, Tin and others
- Spring energized versions for extreme tightness
- Available in shaped forms
- For internal or external pressure
Metal O-Rings capability
- Temperatures from cryogenic (- 270°C) up to high temperatures (+ 900°C)
- Ultra hard vacuum and pressures op to +300Mpa
- Handles hydrogen gas up to non- Newtonian fluids
- Moderate pressure capability
- Lowest leak rate
- Radiation resistant

The metallic ring joint gaskets are manufactured according to the API 6A and ASME B16.20 standards for application at elevated temperatures and pressures. The small sealing area with high contact pressure results in great reliability. The contact surfaces of the gaskets and flange should be carefully processed. Some types of ring-joints are pressure activated, that is, the greater the pressure the better the sealability.
Advantages
* The metal ring joint gaskets have been designed to withstand exceptionally high assembly loads over a small area, thus producing high seating stresses.
Shape and construction
The DONIT TESNIT® ring joint gaskets are produced in several shapes and sizes to meet the most demanding applications.
