Wilwood’s 7/8" or 15/16" bore Tandem Aluminum Master Cylinders available in 3 finishes, plain, ball burnished, and black e-coat. These master cylinders are designed primarily for manual applications and include a pushrod. They’re designed for mount flanges from 3.22” to 3.40”, common measurements for most domestic cars and trucks from the mid 1960s to present, and offer fluid outlet ports on both sides of the bore. The stroke is set at 1.10” with a volume ratio of 2:1 between the primary and secondary chambers. Machined from high-pressure die castings, each master cylinder weighs only 3lbs, a 75% weight savings over most cast iron OE type master cylinders. We also offer a combination proportioning valve kit, which includes brackets and stainless lines specifically for use with this master cylinder, see PN 260-13190, or 220-13189 for retrofit kit.Shipping Notes

Failed at 3 months.
Color: Silver/Battery
I ordered this on Oct 6th. When I first got it, it worked great. I didn't need to use it all that often but here it is, 3 months later, and it is broken. It fails to cut open any cans. Tried on multiple cans over multiple times but it just spins cutting nothing. Total waste of money. Avoid this product if you care about durability or longevity of your purchases.

Works well but doesn't stop on it's own
Color: Green/Battery
The price was decent and I like the color. It is easy to get started and it came with batteries which was unexpected and nice! Like others have said, it doesn't stop on it's own like it's supposed to, which is my only drawback with it. I had thought that if I pushed the button on the top it might stop it, but all that does is reverse the direction of the opener. 4 stars because it does work, but having to fool around with it to make it stop makes it lose a star for me.
