Fits very snug. But good material and the cap somewhat maintains the flat top. The brim is much stiffer, but i hope it will soften up after some use.

For old 4 inch dia. Pipe, it easily blasts away any clogs. The hose is very durable with no worries about it wearing out or down.

Great product. Works amazing. Comes with different nozzles so you can decide which one will work the best. Very pleased with the purchase.
