And with a dedicated team of fluid power experts on-hand to walk you through our wide range of products, sourcing your mechanical tubing and chrome bar from National Tube Supply ensures you get exactly what you need, when you need it.

Chrome Bar

Steel bars are plated with chrome to increase the lifespan of the product by minimizing wear and tear. In fluid power applications, chrome bar is the preferred piston rod material for many types of hydraulic and pneumatic assemblies.

National Tube Supply’s chrome bar products are available in a broad spectrum of sizes, from .500” diameter through 12” diameter and in chrome thicknesses of .0005 and .001 per side. We also offer induction-hardened chrome bar engineered to stand up to the most demanding environments.

Honed Tube

Honed tube is utilized in hydraulic and pneumatic applications, where a tight seal is needed to contain fluid or gas. Precise manufacturing and strict adherence to tight tolerances ensures maximum seal life and minimal leakage.

National Tube Supply carries honed tube in sizes from 1-5/8” OD x 1.250” ID to 16” OD x 14.000” ID and grades DOM ST52.3 or 1020/26 and CDS 1026. Our stock material is honed to a 16 micro-finish, and we can deliver under 10 micro as needed to meet customers’ job requirements.
