FAQ
Q: What is the difference between an Integral Pup Joint and a regular Pup Joint?
A: An Integral is a one-piece forged structure with no weak joints; a regular Pup Joint is usually a separate structure.
Q: Is it suitable for sandy or corrosive fluids?
A: Yes, it is made of wear-resistant alloy steel and a corrosion-resistant version is available.
Q: What lengths are available?
A: Standard lengths are 2–10 ft; longer or shorter sizes can be customized to customer needs.
Q: Is it compatible with international brands?
A: It is interchangeable with major brands such as FMC/SPM.
Q: Does it support OEM?
