API 11B 7/8 quot SH EPT sucker rod coupling
Course T and Course EPT coupling for sucker rods are created as for every API Specification 11B.
Class T coupling use AISI 5140 to manufacture.
Course EPT coupling is used on the base metallic.
The coupling is coated utilizing phosphate chemical therapy or blackoXiHu (West EPT) Dis.de on customer’s ask for.
The couplings are accessible in complete dimensions, slender gap and above measurement.
Mixture couplings are accessible for distinct diameters for each Class T and Class EPT couplings.
