The Prevost ELS 090204 is the coupler half of Prevost’s water system in a 3/4 in body, threaded 3/4 in FNPT. Being unvalved, it flows straight through with no internal valve to restrict it, so you get the full 8.85 GPM rather than the reduced rate a valved coupling gives. The trade-off is that the line drains when you disconnect, which is usually fine on a wash line and not what you want on a pressurised feed.
Note: must be ordered in quantities of 5.
