Models include double-acting, single-acting, double-acting double-ended cap-to-cap and tandem. The Round-Body line offers many different types of piston styles to accommodate any application. Along with our standard piston styles, Flairline offers a "Low-Friction" style that has been quoted as being 'The best on the Market!" No matter what your application, Flairline has a round body style cylinder that will do the job.
