The stainless steel nipples are a small threaded connector while a merchant coupling directly joins two pipes using bolts for a stronger. Additionally, merchant couplings are preferable for permanent commercial/industrial installations.
Stainless Steel Nipple:
- Short length (typically 1-5 inches) of pipe with threaded ends.
- Used to connect two other pipes or fittings together.
- Requires threading connections which takes more time and skill.
- Faster and easier to install than threading nipples.
- Provides a stronger mechanical joint than pipe threads.
- Commonly used for joining dissimilar pipe materials.
