## Description

Rubber Sheet, Buna-N Rubber, Width 12 in, Rubber Length 12 in, Rubber Thickness 1/8 in, 70A

Review: Real Buna-N ? YES! - Real Buna n/Nitrile ! Stable in hydraulic fluid- yes. make my own rubber feet for anything, used little dots I cut with hole punch under cutting board,made gaskets and seals
Review: Stihl Edger Discharge Guard - Perfect! I used this to make a replacement for the discharge flap (sort of like a mudflap on a truck) on my Stihl edger. The factory replacements were on backorder and I was tired of spewing dirt and grass when I used the tool. The old one hardened over the years and finally broke off. The rubber sheet is the perfect thickness, pliability, cut easily and is doing a great job. Very happy with the results and I have enough material left over to make 3 or 4 more if needed.

### ⭐⭐⭐⭐⭐ Stihl Edger Discharge Guard

### ⭐⭐⭐⭐⭐ This rubber sheet got my motorcycle purring again, also works on jars
*by J***L on November 14, 2023*

This is, so far, the best rubber sheet I've gotten this year. I was having problems sealing my petcock to the tank on my motorcycle (a KLR650 / M1030B1) and even fuel resistant gasket maker would not properly seal. I bought this sheet of rubber and cut it into the shape of a gasket and I have had no problems since, no leaks, the rubber (fuel resistant buna nitrile) has not degraded into a gooey mess and most importantly I can ride my bike again and it goes (brbrbrbr) like it should without gas spilling all over it and me creating a fire hazard. See my other reviews for a review of the petcock. As an added bonus, I was able to successfully open a jar of chutney that I was unable to open with my bare hands. This sheet of rubber can do wonders! I couldn't get at the delicious chutney at first, but after wrapping the rubber sheet around the lid and turning USING MY HAND, of course, I was able to access the chutney and spread it onto a naan bread which my taste buds registered as DELICIOUS.
