STANDARD MATERIALS All Rotarex compression fittings are standardly available in stainless steel 316L and raw brass, covering most major application needs. In addition, ten other speciality alloy materials are available upon request for specific applications. Which material is best for your installation? Stainless steel 316L: The recommended option for corrosive gases and high purity applications due to its superior resistance, non-reactivity, exceptional durability and high-surface finish properties. It is compatible with most gas types and low-velocity oxygen applications. Rotarex uses stainless...

SELECTING THE RIGHT FITTING (CONTINUED) THREADS AND END CONNECTIONS Rotarex offers a complete range of thread options compliant with worldwide norms & standards. Please ask us if you do not see what you require. Rotarex thread thread configuration identifcation code International standards for threads and end connections NPT-BSPT Tapered Pipe Thread National Pipe Tapered thread (NPT) - Seal is made on the thread. - Thread angle 60° - Thread sealant is required.

FOR NPT AND BSPT(ISO 7/1) TAPERED PIPE THREADS: Female thread pressure ratings are lower than those for male threads of the same diameter. Take the lower female thread ratings into account when choosing thread dimensions. Pressure ratings change according to thread size, thread type (male or female thread) and material type. Be certain to use the right threads for your application. The chart on the right represents the pressures rates for male and female threads in Brass and SS 316L. Pressure ratings are based on the ASME code for pressure piping B31.3, process piping at ambient temperature Allowable...

SELECTING THE RIGHT FITTING (CONTINUED) ORDERING CODES & OPTIONS Rotarex makes it easy to choose the exact material, diameter, thread size and thread type to meet your specific needs. Each product page has a configuration table where you can quickly find the available dimensions, thread types and the corresponding reference number. Where you see an asterisk (*), you will need to specify the material. See page 8 for available materials and codes. Don’t see what you want? We can custom-manufacture any product to your exact specifications. Just ask one of our engineers. Need help choosing the optimal...

TUBE SELECTION GUIDE - Stainless Steel tubing Different tube diameters, wall thicknesses and material types have different pressure ratings.
