Rawhides sister company Sierra Testing has been assembling high pressure trailers for over ten years. We purchase trailer chassis from nationally known manufacturers like Cheetah. Sierra strives to deliver excellent quality. All equipment meets or exceeds DOT and CFR 49 Compliance’s. We have inventory of tubes and can often respond quickly to meet your needs. While we stock Jumbo tubes of 3AAX-2400, we can custom build trailers to meet almost any customer requirements. Sierra can meet your requirements for manifolds, valving, and placarding.
