MATNIKS Solid Neoprene Rubber Sheets Black 6x6-Inch by 1/16 (Pack of 3) for Pipe Insulation Plumbing Gaskets DIY Material Supports Leveling Sealing Bumpers Protection Insulation

These rubber sheets were perfect for a repair job I had to make on a 35 year old backwater valve for my home. Heavy flooding in my area this past August caused many basements to be flooded due to failing sump pumps or worse from failing or non-existant backwater valves which allowed overflowing municipal sewers to back up into basements. I was untouched but afterwards I decided to inspect mine which hadn't been done in many, many years. Turns out the rubber gasket on the flapper had totally deteriorated and fell apart in my hands when I attempted to clean off all the you-know-what from it. Proccuring a replacement gasket was impossible to find. A replacement flapper with gasket non-existant. I tried 3 different look-alikes as my backwater valve no longer exists on the market. None of them fit properly if at all. So I was faced with 2 choices. Have the basement floor jack hammered open and install a new backwater valve at a cost of several thousand dollars as well as a humungous mess or make a new gasket. I chose option 2. These rubber sheets filled the bill. I traced out what I needed onto one sheet, cut it out and glued it in place with crazy glue. I won't know if this fix is adequate until the next disaster but I'm sleeping better at night knowing at least there is a sealing gasket in the right place as of now. Keeping my fingers crossed.

It came in a timely manner. I have yet to use it in the project that I bought it for.

Used these sheets for vibration absorption on my crummy Rosewill triple monitor mount. I cut one sheet to match the shape of the mount base where it touches the desk. This has the added benefit of protecting my desk from indentations left by the mount. The mount base has two pieces which fit together using 4 bolts to tighten down, but manufacturing tolerances at Rosewill leave much to be desired. At full tightness, the base pieces still had a bit of wobble. The second rubber sheet solved this issue. Placed in between the top and bottom of the mount (with holes cut appropriately for the bolts to pass through), there is no more wobble. The mount feels clamped down properly and solid. I cut the third sheet to fit on the underside of the desk where the clamps of the grommet mount tighten to the desk. This protects the desk and adds another layer of vibration absorption. While I occasionally still see some monitor wobble when typing, the overall effect has been greatly minimized with this easy, inexpensive fix! Only "con" I can think of is the smell of the product being very strong for a few days but it does dissipate somewhat over time.

I bought this for a completely different reason than it's intended purpose. I bought this to sit on top of the tower fan in our bedroom. We bought a new fan that works great, but the control panel is on top and the controls are constantly lit. I'm a VERY light sleeper and the light on the ceiling drove me crazy. Enter this product. I sat it on top of the fan and presto! The light is gone and with zero disruption to the the fan. Works great, stays put, even while oscillating and I sleep like a baby now! Would buy again in a heartbeat!

These were perfect for making new rubber gaskets for the rear view mirrors on my custom street rod.
