CMP Fittings & Custom Fabrications

Standard and customized fittings to meet your project requirements.

Standard fittings such as tees, wyes, elbows, saddle branches, manifolds and reducers are available for Contech Pipe and Pipe-Arches. Special fittings, including manholes and catch basins, can be fabricated to meet your needs. Prefabricated fittings can be designed and constructed to efficiently meet project requirements.

HEL-COR Strip-Perforated Pipe Fittings are furnished in the shortest lengths possible, but with sufficient length for attaching standard connecting bands. Bends up to five degrees can be made in one or two standard connecting bands due to their flexibility. Connecting bands are corrugated to match corrugations in the pipe and ensure strong joints.
