Grow1 Combination Tee - INS x INS x 3/4-in FPT - 17mm - 25 Count

Branch a 17mm Drip Line to Threaded Fittings - 25 Tees

Splitting a drip or hydroponic water line onto a threaded outlet usually means stacking several adapters, and each added joint is another place to leak. This combination tee does it in one fitting: two insert ends connect 17mm tubing run to run, and the branch has a 3/4-in female pipe thread for a threaded connection. One part makes the junction.

This unit holds 25 tees, which suits growers building out multiple zones or rows, or keeping spares on hand for repairs and system changes. Hobbyists with a single small system will have plenty left over.

Key Features & Benefits

• Two 17mm insert ends — connect tubing runs on both sides of the junction.
• 3/4-in FPT branch — accepts matching male threaded fittings for valves, risers or adapters.
• Combination tee design — joins insert and threaded connections in one fitting, reducing the number of parts.
• 25 tees per unit — stocks a multi-zone build or repair kit in one purchase.

Who Should Use Grow1 Combination Tee

Growers running 17mm drip tubing who need a threaded take-off, from home hydroponic setups to larger commercial irrigation layouts.

Frequently Asked Questions

Q: What are the connections?
A: Two ends are 17mm inserts and the branch is a 3/4-in female pipe thread (FPT). The inserts go into tubing and the branch takes a male threaded fitting.

Q: How many tees do I receive?
A: The unit is sold each and contains 25 tees. You do not need to order 25 separately.

Q: What does FPT mean?
A: FPT stands for female pipe thread. The threads are on the inside of the fitting, so it mates with a male threaded part.

Q: Can I use it for a straight connection?
A: No. A tee creates a three-way junction. Use a straight coupling if you only need to join two tubing ends.

Q: Should I seal the threaded branch?
A: Thread sealant or tape is common practice on pipe threads to help prevent seepage. Follow the instructions for the mating fitting.
