Proco Style R-6201
The Proco Style R-6201 flexible metal reducing connector has been designed to control a variety of mechanical stresses, such as:
- Vibration control
- Noise reduction
- Relief from system stressors
- Prevention of system shock
- Compensation for misalignment and movement
Ordinary flexible metal hoses can fail to operate properly when subjected to high pressures; adding a flexible restraint, such as a metal braid, allows the hose to adequately withstand the specified internal pressure and prevent elongation. The woven metal braid is designed to fit over the metal hose, and to be strong enough to withstand elongation up to the full pressure rating of the hose.
Flexible hoses and braids can be made from a variety of different metals, to suit even the most diverse needs.
For more information about the features and benefits of the Proco Style R-6201 flexible metal pump connector, download our brochure.
Other reducer types are also available. For more details or for up-to-date pricing and availability information, contact PROCO today.

Temperature Correction Factors
1. Determine maximum operating temperature.
2. Locate appropriate correction factor above.
3. Multiply maximum working pressure by correction factor at temperature for acceptable rating.
Service temperature for a braided flexible metal pump connector has a negative affect on the amount of maximum pressure to which it can be subjected. The table above should be used to calculate the safe working pressure based on the elevated temperature the braided metal pump connector is operating under. (Working Pressure X Elevated Temperature Conversion Figure = Safe Working Pressure.)
Correct placement is essential to the proper functionality and lifespan of a flexible connector. For best results, place the Proco Style R-6201 flexible connector adjacent to rotating equipment, in a straight line, without any offset, to help isolate the piping system from excessive vibration and noise.
Braided flexible metal connectors must be installed at or below the listed permanent lateral offset values listed in the Proco R-6201 Brochure.
For more detailed information, download the PROCO Style R-6201 Brochure.
The information in the table below is to be used as a guide for the proper selection of braided metal pump connector materials (both hose and braid), based on the chemicals used.
This data should not be construed as advice on which combination to use, or not use; final responsibility lies with the system designer or operator for correct material selection based on flow media.
It is suggested that you include flow media information on the “Connector Specification Data Sheet,” found at the back of the PROCO R-6201 Brochure.
