2. Flow pin selections marked "FP" are followed by a numerical value equivalent to the maximum flow rate (in atm cc/sec.) at 15 psia pressure differential. Flow pin selections marked "SP" contain a linear and an exponential numerical value (ie. SP52 is 5 x 10+2 (or 500) std. cc/sec maximum flow rate at 15 psia inlet pressure.

3. The inline body style is only available in stainless steel and with 1/8" female NPT fittings 180 degrees apart. An ordering example would be EP-SS-60-FP20.

Larger flow pins are available upon request. Flow rates up to and over 8000 cc/sec can be accomodated.
