Need advice for this Adaptor remover (home plumbing)

[Ephant]

Is there any tool that can grip the yellow threads and turn it? I use pliers but they are very small. I even used vise grips but the teeth are very small. There is a rubber gasket inside the yellow plastic adaptor which has female thread on top (the male thread at bottom is for 1/2" conversion). The faucet is 3/4" and has male thread. I tightened the 3/4" plastic adaptor with my hands but can't remove it. For this situation. Mechanically, Is it because the faucet thread and adaptor threads are not compatible or more about the gasket causing it to tighten?

Or if the description above is vague. Just please tell me what kind of tool that can engage the threads. Pliers and vise grip have small close teeth.

Use a pipe wrench. They tighten their jaws when you turn them (in the correct direction)

The teeth of wrench are very closedly space. Is there other tool that can do it?

I just used saw to cut the adaptor and destroy it just to remove it.

Who cares?! Use a pipe wrench. That is what they are good at.

The teeth of the wrench don't have to mesh with the adapter teeth. All you have to ...

never mind...

I have 5 pieces more like it.. used it in washing machine and water filters.

The problem with pipe wrench is it's pure iron and can damage the plastic threads.

So I'm looking for something like the following close wrench in pic but adjustable. Is there anything like an adjustable close wrench that is also plastic? Iron is ok, at least the force wouldn't be concentrated on a few plastic threads on the adaptor only.

If there is none yet a market. Can you design an adjustable close wrench?

Also it made me think. Do all the tools in the International Space Station already in the market or do they made it custom a round close adjustable wrench?

That is nonsense. The pipe wrench may leave some small scars on the outer part of the plastic assembly, but it will not do anything to the threads on the inner part of the assembly.

My preferred solution, at least for a first attempt, is a pair of grippy gloves. I keep a pair in the kitchen, and a second pair in my shop. They both get plenty of use. They do two things - shield my delicate fingers from sharp edges so I can grip harder, and increase friction so I can get more torque from the same clamping gripping force.

I also have a pipe wrench for the really stubborn cases.

I meant I didn't want to leave some small scars on the outer part of the plastic assembly. How do you call those outer part? In wheels in cars/vehicles, the outer part of tire is called threads so I mention threads. What is the right term then?

Why did you give picture of 18" pipe wrench? Does the 18" mean it is the opening of the wrench? If i'd buy one, maybe a 2" is enough? The heavier one may be so heavy it may pull the entire faucet off the PPR piping when turning it.

Why not? You were willing to destroy one of them.

The wrench is meant to be applied to this part, not the threads.

Tires have treads.

Pipe fittings have threads.

I think a pipe wrench is overkill.

I use channel locks:

 

[Ephant]

I borrowed a pipe wrench as well as ordered both the channel lock and a pipe wrench.

However, even if I used a pipe wrench, the tap adaptor still leaked! Then I realized why, it's because the NPT in the faucet is not compatible with the GHT of the tap adaptor. See:

https://homeandgardentalk.com/ght-vs-npt-compatability/

I used the faucet to the sediment filter connected to the clothes washing machine.

Has anyone used this kind of setup? First, some terms we should agree with first.

1. Do you also call it as faucet tap adaptor (the yellow one I sawed earlier)? It's GHT which is not compatible with the faucet NPT so either I'll get a converter or replace the faucet (which is connected to the PPR female NPT thread).

2. Do you also call the hose connector as Water Hose connector quick release? What else do you call it? Or haven't you seen anything like it?

3. The sediment filter is GHT. I connected the washing machine water hose directly to the sediment filter via a 3/4" male to male adaptor.

4. Ok. What other ways to do it? How did you set up yours? The washing machine could another output like a plain kitchen sink faucet, etc.

Appreciated all your help. Thank you!

It seems that no one has yet suggested pouring a kettle full of hot water on the connection.It could very well be undone by hand after that treatment.
