INTERCHANGEABILITY
OTG tube fitting are manufactured to be completely interchangeable with other leading tube fitting manufacturers. Testing and the exceptional quality of the products assure 100% reliability when intermixing component parts of compatible makes and brands.
NOTE
When ordering tubing, remember, tube fitting are designed to be used on similar tube materials. (i.e. stainless on stainless, brass on copper, steel on steel, etc.)
HARDNESS INFORMATION
In general metal tubing should be fully annealed to work properly with D-LOK tube fittings. While most stainless steel tubing is restricted to a maximum ROCKWELL HARDNESS of Rb90, many users specify that this hardness be further restricted to Rb80. Such tubing lowers the installed cost because it is more easily bent and installed. While D-LOK stainless steel tube fitting may be used on stainless steel tubing with a hardness of Rb90 maximum, We suggest that whenever possible, specify a maximum hardness of Rb80. Refer to Table 1 on this page for working pressures of tubing by material and size.
CAUTION
Use of dissimilar fitting and tube materials can lead to a dangerous situation!
WALL THICKNESS
The wall thickness selection should be based on the operating pressure, temperature, and shock conditions.
TUBE SELECTION
Poper tubing selection is essential to the performance of a tubing systeam. Consider a systems pressure, flow, temperature, environment, and compatibility with the process fluids when choosing the tubing material, size, and wall thickness.
