C710 series couplings are machined using solid steel bar stock, are zinc-plated, and come standard with buna-N (Nitrile seals).
Type 304 stainless steel balls, retaining rings, and springs maximize corrosion resistance and extend service life.
C710 series couplings are designed for heavy-duty operation in offshore drilling and construction equipment and comply with Det Norske Veritas North Sea standards for coupling applications.
