DELCORTE Tubing and Casing Couplings are produced from API approved seamless stock.
To assure dimensional accuracy, true thread forms and consistent conformance to API specifications,
all DELCORTE SA couplings are 100% produced on numerically controlled machines that are 100%
bored and tapped in a single chucking. Unless otherwise specified, all DELCORTE SA couplings
are 100% zinc phosphatized with internal thread further protected and lubricated with a
water-displaced oil coating.
