The Best Compressors on the Market Today

Compressors are relieved on the bottom for wire O-rings and Type 3 anodized for long life. Bore sizes are prominently engraved in 3/4" numbers for easy identification. Standard stocking sizes range from 3.552" to 4.750" and 75mm to 95.5mm. Sold individually.
