DV Series Double-Acting Pneumatic Cylinder, Universal Mount, 1.13 Inch Bore, 0.38 Inch Rod, 2.00 Inch Stroke, 1/8 NPT Ports

This pneumatic cylinder comes with M45 mounting nuts, and you get two of 'em.

For hookup, it uses 1/8 NPT ports, so your air fittings and lines need to match 1/8 NPT on the cylinder.

Buna-N U-cup seals are standard on the piston and rod, which work well for standard compressed air systems. The temperature range runs from -20F to 200F and max pressure tops out at 250 PSI. Those are the operating boundaries the cylinder is built around, so as long as your application stays within those numbers you should be in good shape.
