As previously stated, the
interference fit establishes metal to metal contact between the tube and fin and provides TCC.
It fits factory triggers well and tends to be a little too large for the frame, developing a nice

Another enhancement involves

interference fit between band surfaces on both parts.
(15-17) In this design, early fixation is obtained with a combination of peripheral peg cementation combined with the

PVC fittings have a slightly tapered "
interference fit." If you apply cement and press the pipe and fitting together but let go before the weld is complete, the taper will "spit" the pipe out slightly.
A tight
interference fit between mating parts is obtained by shrinking-on, that is, by heating the outer part to expand the diameter for easy assembly and then cooling so that the outer part contracts.
You will not need an
interference fit for these parts, but you do want a zero clearance.
