Tubing Anchor
An anchor set at the end of the tubing that holds the string in place.
What it does
Limits tubing movement as it stretches on the plunger downstroke and compresses on the upstroke, which cuts helical buckling and plunger on tubing wear.
Basics

Troubleshooting
- Symptom
- Plunger and tubing wear faster than expected
- Likely cause
