Interesting 1" CPVC coupler find.

So I guess depending on where you live and the hardware stores nearby, we now have quite a few ways to reduce 1-1/4" PVC to 1/2"
1) 1"x1/2" PVC bushing
2) 3/4" PVC coupler (some 3/4" fittings have larger OD than 1" PVC) + 3/4"x1/2" PVC bushing
3) 1" CPVC coupler + 3/4"x1/2" PVC bushing
The first one depends only on the ID of the 1-1/4" pipe on hand, the next 2 depend on the OD of the bushing and ID of the pipe.
ABS pipe might also have consistently different wall thickness than PVC pipe as well, as the schedule rating only specifies a minimum wall thickness.

I order one for a 1-1/4" plunger tube gun I'm in the process of making and I'm wondering if this connecter makeitgo has created has any advantages I should know about.

Does anyone use these?

I have not heard of people using those. Makeitgo's method doesn't really have any advantages, except that you don't have to wrap the reducer in tape. It's decidedly more expensive than the most common method of ending your 1.25" PVC plunger tube, which is a 1" x 1/2" reducer wrapped in smooth packing tape and gooped and screwed into your plunger tube. The method just named makes less dead space than the version you are suggesting.

Ahem.I have not heard of people using those.
Advantages: easier to disassemble, no tape required, can be held on with screws.
Disadvantages: slightly greater dead space, a slightly greater chance of the front bushing assembly flying off the front of the blaster.
I hate using tape and adhesives and prefer simple assembly, so I've always built this way (as opposed to the now standard 1" bushing).

An advantage that you've ignored with makeitgo's method, is that it's flush with the tube, so you can have stuff slide over your plunger tube if you need to.I have not heard of people using those. Makeitgo's method doesn't really have any advantages, except that you don't have to wrap the reducer in tape.
And if you haven't seen anyone using a 1 1/4" x 1/2" reducing bushing you don't read too many topics here I guess.

The lip on a 1"x ½" PVC reducer can be ground down with a dremel to enable sheaths to slide over it.An advantage that you've ignored with makeitgo's method, is that it's flush with the tube, so you can have stuff slide over your plunger tube if you need to.
Do not misunderstand. I am in no way belittling Makitgo's find. I am merely saying that the 1"x ½" reducer is more expedient for several reasons.
- It is more widely available: the 1" CPVC coupler is scarce at smaller hardware stores.
- It is less expensive. The combined cost of the 1"CPVC coupler and the ¾" x ½" PVC reducer is more than the 1"x ½" PVC reducer. (The cost of a dab of goop and a few inches of tape is negligible.)
- It requires less work.
And if you haven't seen anyone using a 1 1/4" x 1/2" reducing bushing you don't read too many topics here I guess.
I have read quite a few topics. I just don't note every inconsequential detail. I rather, try to figure out what is going inside the blaster.

(Also you seem to be confusing the discussion on using a 1-1/4"x1/2" bushing + coupler, and what you're talking about with the 1"x1/2")

I'm not knocking the 1" x 1/2" reducing bushing, as that is usually always what I use for this. Instead of grinding down the lip, you can often just hammer it straight into the 1 1/4" you're fitting it in. I still use tape to make sure it seals because the lip doesn't always seal perfectly with the 1 1/4".stuff
I also have to disagree that it's easier to find, I mean I assume it is for you. I've only seen the round-style bushing from Home Depot, and they don't carry them sometimes, or at certain stores. I do notice they have the round-style ones on their website, but I'm not sure they'd just swap it out for a hex one if they didn't carry the round ones.
I've seen 1" CPVC couplers at Menard's (probably not by you), several Ace's, and all Lowes that I have been to. Again, I guess it just depends on what you can find locally and what stores are close to you.
I also fail to see how it takes more time to do. You throw in the reducer in the 1" coupler, and just hammer it straight into the plunger tube. Last time I checked that is easier to do than getting it to seal perfectly with tape.
Strongly agree with Carbon here. That is one huge advantage. Assuming you find the magical sized 1" CPVC coupler, makeitgo's method is much easier and faster to get your bushing to seal perfectly.I hate using tape and adhesives and prefer simple assembly, so I've always built this way (as opposed to the now standard 1" bushing).
Sure, it's like a $1 more expensive, but I'll always spend extra money to save time and dicks in my mouth.
