Loc-Line flexible modular hose offers endless plumbing configurations and is useful for unique plumbing designs. Loc- Line Modular plumbing is most commonly used on return lines and closed loops where it is important to direct the water flow in a particular direction.
- For 1/2" Loc-Line NPT connector use 1/2" threaded bulkheads
- For 3/4" Loc-Line NPT connector use 3/4" threaded bulkheads
Have a great day!
In order to connect the loc-line to a bulkhead or other plumbing you will need Loc-Line Male NPT Connector, found here: https://www.bulkreefsupply.com/loc-line-male-npt-connector.html. The 3/4" npt connector will fit 3/4" plumbing/bulkheads.
Yes, the bulkheads and all of our plumbing parts with threads are all NPT standard and will fit together.
Idea for you guys maybe make a bit+bulkhead+NPT connector starter kit.. Just a thought, it would buy it.
If you want to use the 3/4" NPT loc-line adapter then your best bet would be to use a 3/4" threaded bulkhead. That way you don't need any adapters, etc. Which size drill bit depends on which type of bulkheads. (abs vs sch80) but assuming your typical ABS 3/4" bulkhead your looking at a 35mm drill bit.
It depends on which fitting you purchase. If your purchase the 1/2" version then it will have 1/2" NPT threads and if you purchase the 3/4" version it will have 3/4" NPT threads.
