Gaggle of Gaskets
Black neoprene gaskets in a variety of sizes and shapes: loops, hoops and flat. Stretchy, a little dusty, but in good condition. The Small Round assortment gets you (2) gaskets, between 1/2" and 3/4" dia cross-section, in loops with overall diameters between 1 and 3 feet. The Large Round assortment is one gasket, 5/8" to 1" dia, in a 4 to 9 foot dia loop. The Flat assortment is pieces that make loops of 2 to 5 feet dia. The rubber is about 2" x 1-1/2", but the shape varies: could be square, grooved, V-shaped, or something else. Use as is for really big valves, or better yet, chop it down to size. A great way to get cheap rubber materials for your non-critical applications We'll pick the exact dimensions and, in the case of the Flat assortment, the shape you get.
