Great product By Curt on 2/17/2018
Curt would recommend this product to a friendI found them hard to snap together and did not want to purchase tool to help snap them together for one time use. I did eventually get them together on the ground, after that I put them in the tank. I am also short with a deep tank. -

Good product but order extras By Ryan on 4/14/2014
Ryan would recommend this product to a friendI purchased two of these 1/2 for my sump returns. I was installing them with the wye connector and as I was screwing them into my pvc return, I broke on right off at the threads. I now need to purchase a second one and there is no-one that has them local, so now I need to purchase a single unit for ~2.00 and ship it out. Spend the extra 2 bucks up front and purchase an extra one. You will also need the snap together tool. -

Are the threads on these the same as on the threaded bulkheads?
Question posted on Jan 13, 2014 6:00:00 AM
Hi Miles,
Yes, the bulkheads and all of our plumbing parts with threads are all NPT standard and will fit together.

I have a 1" bulkhead and dont know how I would transition to the 3/4" NPT and the 3/4" lock line.
Question posted on Jan 8, 2017 10:41:00 AM
Great question! If your 1" bulkhead is a slip fitting, you will need the SKU: 208392. This fitting will slip into the bulkhead and convert to 3/4" female thread. From there, all you need is the 3/4" NPT x Loc-Line fitting. These products are listed in the links below. :-)

I’m but the 1” bulk head what size do I need for this so I can get loc line return
Question posted on Nov 19, 2017 2:54:00 PM
You will need a 1" to 3/4" reducing bushing to put into your bulkhead, and then the 3/4" NPT adapter for loc-line. That will then screw into the 3/4" bushing and you can attach more loc-line segments as needed onto the adapter.
Answer by: Charlie (Admin) on Nov 20, 2017 2:22:00 PM
All npt fittings are designed to work with the corresponding pvc size. If you are using a 1" bulkhead, you'll want to get a 1" to 3/4" reducing bushing to be able to use the 3/4" npt loc line adapter.

Hello, I wanted to know what size bulkhead should i use, i have the 3/4" NPT connector? Also what size diamond bit should i purchase to make the hole for the bulkhead?
Idea for you guys maybe make a bit+bulkhead+NPT connector starter kit.. Just a thought, it would buy it.
Question posted on Jan 11, 2014 8:46:00 PM
Hi Chris,
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.

Which side of the Loc-Line is 3/4? Does it screw into a 3/4 fitting?
Question posted on Mar 30, 2015 6:40:00 PM
Great Question Linton!
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.

What is the thread size on this product?
Question posted on Sep 23, 2013 10:10:00 AM
Hi Allen,
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.
