Product Description
Product Overview
API SH Type Grade D 40Cr material polished steel rod couplings designed for sucker rod applications with corrosion resistance and lengths ranging from 25 to 30 feet. Manufactured in compliance with API Specification 11B standards.
Key Features & Manufacturing Process
- Cold form rolled thread cutting creates compressive stress at thread roots for maximum strength
- Available in full size, slim hole, and over size configurations
- Combination couplings available for different diameters (sub-coupling)
- Class T couplings manufactured from AISI 5140 steel with phosphate or black oxide coating
- Class SM couplings feature spray metal hardening process for enhanced durability
