After years of being successfully incorporated in Flow-Rite watering systems for lead-acid batteries, the company is marketing their couplers as a separate product line. The couplers are made of high-grade UV resistant polypropylene, non-swell Viton O-rings and stainless steel springs.  These materials were carefully selected for their aversion to corrosion and acidic degradation. The couplers are also capable of gamma sterilization. The design permits for the highest flow rate of comparable couplers. The pressure range is 0-100 psi, with a temperature range of freezing to 160 °F (71 °C).  Disconnecting is hassle free with the ergonomic push-in button.  Exclusive keyed connection options are offered for error proofing.  Valved and straight through versions, as well as multiple barbed and threaded terminations are also available.  Other options include private labeling and custom colors. www.flow-rite.com
