SURGEx S20-A is a size A, pre-charged, surge pressure absorber (also called Water Hammer Arrester (WHA) or surge arrester. SURGEx-S series is fabricated from stainless steel grade 304 as standard and is fitted internally with stainless steel bellows. The end connection of SURGEx-S20-A is male threaded size ¾” according to NPT. SURGEx-S series can withstand pressures up to 400 PSIG (27.6 BAR) and temperature range from -100°F to 300°F (-73°C to 149°C).

OPERATION
SURGEx-S series water hammer arresters use stainless-steel bellows as the main component to absorb the shock waves caused by water hammer. When a water hammer occurs, the bellows compresses as water rushes into the arrester, creating a cushioning effect that absorbs the pressure surge. As the water flow slows down and pressure stabilizes, the bellows returns to its original position, ready to absorb the next water hammer.

      Works good but have only tried it on fine setting.
      Works good but should have an overall cap as seasoning gathers around the inside.

      Great Value!
      Color: Tall Set - Black White
      Better than anticipated. These are sturdy and work very well. They came with a little funnel to fill, but easy enough without it. They are attractive, I keep on top my stove as I have room. Grind well.
