Strong Back RC 5000 Series Couplings

When underground pipes face heavy earth loads, shear forces, or corrosive soil conditions, standard couplings can fail. VANRON 5000 Series Strong Back RC couplings are engineered for these extreme environments.

Features

  • Superior corrosion resistance – Unlike standard 301 stainless steel, our clamp bands are 316 stainless steel, offering better protection in coastal areas, chemical environments, and aggressive soils.

  • Crush resistance + pipe alignment – A 0.012″ 300 series stainless steel shield wraps around the coupling to resist heavy earth loads. The molded-in bushing keeps pipes centered even when shear forces try to shift the joint.

  • Engineered for large diameters – On 6″ and larger couplings, two nut-and-bolt take-up points per band provide even compression across the entire joint – no over-tightening one side while the other remains loose.

  • Built to code – Conforms to ASTM C 1173, CSA B602, and ASTM D 5926.
