You could use a hose tail?

No I'm thinking of a 110clear acrylic tube to a 110 pressure joint

i've made calcium reactors for marine reef tanks with cast acrylic tube and edge bonded ABS joints using TENSOL 12
so acrylic and pvcu should work in theory, i'd do a test piece edge bonding to test strength.
but you can buy clear pvcu in 110mm though not as clear as acrylic

Acrylic is a difficult material to solvent weld but yes you can if you treat it as if it was PVC pipe as per the guide below:
How to make good glued joints:
Weld-On 725 Wet'R'Dry solvent cement is an excellent glue for either ABS or PVC pipework and is ideal for pipework up to 2" (63 mm) for those who can work quickly and with confidence. However, application and assembly of joints should be completed within about 15 to 20 seconds so it's too fast for those who are inexperienced and need extra time, especially on larger pipe sizes or in higher ambient temperatures.
When Wet'R'Dry is used on ABS, hold joints together for a few seconds to allow setting. When used on PVC, hold joints together for at least 30 seconds to prevent the pipe pushing back out again especially with looser fitting joints.
Tangit PVC-u is a slower setting glue so application and assembly can be done more slowly as long as it's completed within about 30 to 60 seconds.
When Tangit is used on ABS, hold joints together for 30 seconds to allow setting to begin. When used on PVC, hold joints together for one minute but reapply pressure if the pipe shows any signs of pushing back out.
With either type of cement, use a solvent cleaner which is NOT just a cleaner, it prepares the surfaces and ensures that the glue penetrates and makes a good weld so it's essential, not optional, if you want good joints that don't leak!! Since the solvent cleaner dries quickly, especially on PVC, the timing is important and the cement should be applied as soon as possible after the cleaner before the softened surfaces have time to dry and become hard again. Have everything ready, apply the cleaner then apply the cement then push them together.
With either type of cement, before applying the cleaner, roughen up PVC fittings and pipe surfaces with sand paper. After the joint is made, allow 15 minutes setting time for ABS pipework or 30 minutes for PVC pipework before putting under pressure.
If you slightly chamfer the end of the pipe. It doesn’t make any difference whether you twist it to make it slightly easier to push it into the fitting or whether you push it straight in.
