One of my customers recently contacted me before placing an order. He had done his homework, measured his valve, compared products on Amazon, and still wasn’t convinced he was buying the right parts.
His questions turned into a great reminder of how confusing IBC fittings can be—and why taking a few extra minutes before ordering can save hours of frustration later.
Question #1: Why Doesn’t My Valve Match the CamLock Dimensions?
The first thing that caught his attention was the size of his valve.
After carefully measuring the outside diameter, he came up with 2.4375 inches. However, the female CamLock connector he was considering listed an inside diameter of 2.51 inches.
Naturally, he wondered:
“How can a fitting that’s larger than my valve possibly create a watertight seal?”
He even included this note in his email:
“The inside dimension of the CamLock is not clearly provided. The left side of the white arrow extends past the inside. How is 2.53 inches the correct size for my male connection, which is less than 2.5 inches?”
He wasn’t missing anything.
In fact, he was asking exactly the right question.
The answer is that CamLock fittings aren’t designed to seal based solely on their published inside diameter. When the cam arms are closed, they compress the gasket around the male adapter, creating a tight, leak-free seal. The slight difference in measurements is completely normal and is built into the design.
His careful measuring actually gave me confidence he was on the right track.
Question #2: Why Buy an Eight-Piece Kit When I Only Need Two Parts?
His second concern made just as much sense.
He only wanted:
One CamLock fitting
One brass shut-off valve
The Amazon kit I recommended contained eight pieces, and he understandably felt it included a lot of parts he would never use.
He wrote:
“The attached picture that contains 8 pieces is overkill as I just need the two at top left, the CamLock and the brass valve.”
I agreed.
If someone only needs two parts, buying just those two sounds like the obvious choice.
So I decided to see if I could find a better option.
The Surprising Discovery
Having sold on Amazon for years and being familiar with these products, I assumed finding two individual parts would be simple.
It wasn’t.
After spending much longer than expected comparing listings, I discovered something surprising.
Buying the CamLock fitting and brass valve separately actually cost significantly more than purchasing the complete kit.
Even though the kit included several parts most people would never use, it was still about half the price of buying the two pieces individually.
Sometimes the better value isn’t the product with fewer parts—it’s the one that’s packaged more efficiently.
One Last Compatibility Problem
After our discussion, the customer found two individual parts he liked and asked if they would work together.
Unfortunately, they wouldn’t.
Although both were labeled 3/4 inch, they used completely different thread standards.
The CamLock fitting had 3/4-inch garden hose threads (GHT).
The brass valve had 3/4-inch pipe threads (NPT).
Those thread types are not interchangeable.
To make matters worse, both fittings had male threads, meaning they couldn’t physically screw together even if the thread standards matched.
This is one of the most common mistakes people make when shopping for IBC accessories.
Just because two products share the same nominal size doesn’t mean they’ll connect.
The Final Decision
Once I explained the thread differences and showed him why the complete kit offered better value, his decision became much easier.
His final email said:
“Thanks, Will. I very much appreciate your input. We will order the kit you recommended.”
The Takeaway
This experience reinforced something I’ve seen countless times.
Shopping for IBC accessories is often far more complicated than it appears.
Product listings can be confusing. Measurements can seem contradictory. Thread standards can look identical while being completely incompatible. Even experienced DIYers can end up ordering parts that simply won’t fit together.
That’s why I always encourage customers to ask questions before placing an order.
A few clear photos of your valve can often tell me everything I need to know.
I’d much rather help you buy the correct parts the first time than watch you spend money returning the wrong ones later.
If you’re unsure which IBC CamLock fitting or valve is right for your tote, send me a few photos. I’ll gladly help you choose compatible parts before you click Buy Now.
