SURGEx S25-F is a size F, pre-charged, surge pressure absorber (also called Water Hammer Arrester (WHA) or surge arrestor. 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-S25-F is male threaded size 1” 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.

    Love it
    Color: Dark Green, Size: Small
    I got the dark green. Love the sweater and it's warm. I do layer the sweater as well. It is as pictured. Size is perfect to me. I like sweaters to be longer and a bit wider in case it is freezing and I need to layer it. This sweater is perfect for layering. It comes closer to my backside, it is a little wide and not snug, and I like that the sleeves come over my wrists

    Still soft but looks terrible after 1 wash. Save your money
    Color: White, Size: Small, Color: White, Size: Small
    Update: sweater looked great when I received. After 1 wash it looks terrible. Looks like it’s been washed too many times, material fuzzy and piled. After wearing it once, it snagged and the knit pulled through. I would NOT recommend. I had such high hopes. Save your money. Very nice sweater, especially for the price! I love the details of the buttons on the sleeves. It is SO soft. It’s not super thick as I can see my skin through it when pressing my hand up against fabric. However, it’s not see through when wearing it. It’ll be perfect in cooler weather and perfect in the winter with a coat but won’t cause me to overheat when in a heated environment. I do feel like it runs big. I could have sized down a size. Although I’m not sure if it’ll shrink after a wash or two.

    Disappointed.
    Color: Blue, Size: Large, Color: Blue, Size: Large
    This sweater is so comfortable and very soft. It fits well in a flattering, oversized way. But after one wash it is pilled everywhere which makes it look old and shabby. It’s at a price point where I feel compelled to return it.

    Perfect for casual wear and dressy style
    Color: Dark Green, Size: Small
    This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.

    Love the long sleeves!!!
    Color: White, Size: Small
    Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.
