CLASS T Sucker Rod Couplings
The coupling blanks are manufactured or machined to the required dimensions and tolerances. They are then threaded using a cold-forming rolled thread tap and given a coating to enhance their anti-galling and lubrication properties. For applications that do not involve abrasion or corrosion-abrasion issues, it is recommended to use class T sucker rod couplings during installation.
Sucker rod couplings are offered in both API full size and slim hole configurations. Upon request, oversize couplings can also be provided.
CLASS SM Sucker Rod Couplings
The process of Spray Metal involves applying a nickel, chrome, boron, and silicon-based powder onto a base metal before melting it. This results in a hard, uniform, and highly corrosion-resistant surface with a very low friction coefficient. The Class SM sucker rod couplings are a suitable choice in situations where there is a problem with corrosion or abrasion. Our sucker rod couplings are available in both API full size and slim hole versions, and we can provide oversize couplings upon request.
