Replacement washers for vintage combination bags

I hope this has not been addressed before, I tried searching for it, but I could not find a thread on this subject. If I am "late to the party" on this I apologize.

If you like combination bags vs a fountain syringe, like me, you have come across the problem of the rubber sealing washer on the tubing adapter getting hard and leaking. It is no fun to take an enema while a large portion of the water is running down the hose to get you wet, or dripping on the bed. Exact replacement rubber washers are impossible to find but it is possible to buy an off the shelf washer and slightly modify it to work. Lowes sells stock washers in plastic bags, in their hardware section in some drawers along with specialty fasteners. The brand is: Hillman part number: 880372 size: 7/16" X 1" x 1/16" thick. The bar code on the bag is: 0 08236 70764 9. The inside diameter of the washer is correct, and the thickness also works but you will need to trim down the outside diameter. You can do this by laying your old washer on the hew one and drawing on the new washer with a ball point pen (the older style pens seem to work better than the new ones). Take a sharp pair of scissors and careful trim the outside of the washer to match the old washer. The come quantity 2 to the bag so you might get 2 bags in case of errors, or for multiple enema bags. You can do a GOOGLE search, you might find them online if you do not have a Lowes store near you.

HAPPY HOSING!!

Although not flat, an O-ring would probably do the job.

They come in all sizes and are available everywhere.

You can also use a couple seals for garden hoses, they're rubber and flat.

EBay may have some replacement parts. I once bought a vintage jar of Vaseline off of that site.

You can go to an auto supply and buy gasket material, typically some kind of rubber, various thicknesses. The sheets were typically about 4 inches square. Ive not seen silicon rubber, but who knows, hate leaky enema bags.

Amazon has silicone sheets in different sizes and thickness.

I'm not sure about washers. However. How old is this plastic bag? Is it deteriorating? I remember the smell of the red combination bags. They reeked of chemicals. Just a thought about what chemicals are going straight into your colon when using these old bags... Silicone is readily available now. Just sayin.
