What size Loc-line do i have?
It seems like a simple question to answer, but for anyone who has tried to figure this out, it doesn’t always seem clear. You’ll find loc-line in use in just about every saltwater aquarium and it’s used as a means of directing water flow on your return line. The hobby is full of all kinds of different attachments, accessories and nozzles that snap right on to the end of your loc-line, including our own Random Flow Generator, or RFG Nozzle.
When it comes time to choosing the right size it can be hard to tell what you need – especially if you only have access to one of the two most common sizes; 1/2” and 3/4” loc-line.
To make matters worse, if you were to try and measure your loc-line, you’re likely to get a measurement that seems confusing. For instance, the 1/2in loc-line is a little more than 3/4in across.
So, how can you tell what size you have? Here are a few tips to help you properly measure your loc-line.
The size of the loc-lin refers to the inner dimension or ID as opposed to the outer dimension or OD.
When measuring loc-line, use these numbers to determine what size you have.
If all else fails – stick your finger in it!
It’s not the most exact method, but if you can fit your index finger in it, or at least most of the way in, it’s probably a 3/4in lock-line. If you can’t and the opening is too small, then it’s probably the 1/2in variety.
We hope this quick-tip helps you figure you your lock-line. and the next time you have to measure loc-line, you can do it like a pro.
What Type of Nozzle Should You Attach to Your Loc-Line?
Well, that’s easy – a Random Flow Generator Nozzle of course.
