Said to be demountable. Are they reusable?

Provided they are not damaged I dont see why not,but why would you ?

These fittings are 15mm. 3/8" equals 9.525mm So the answer is No.

Do these require an insert with plastic pipe ?

Yes, it is advised with the 15mm fittings. Let me know if you want a link so you can order them together? Regards Andrew @ Cool Products, Oxfordshire Tel - 07879 407 664

can this be attached to copper pipe already in place leading to a radiator?

Yes - this is suitable direct to copper - no insert required- just click straight onto pipe / ensuring it's pushed on fully and tightened securely
