MD PVC Coupling for Central...
$6.99
Product details
Part 507 is the plain PVC coupling that joins two lengths of central vacuum pipe end to end, which is how a stack of short tubes becomes one continuous line. It is the simplest fitting in the range, and an installer ordering by the case enters a quantity of 175.
Repairs use the same fitting the other way round. Cut a damaged section out of an existing run, and a coupling at each end splices a fresh piece into the gap. A handful of spares in the van costs less than losing half a day to one missing fitting.
PVC vacuum fittings are solvent-welded rather than threaded, so a joint is permanent once the cement has set. Dry-fitting the coupling with both pipe ends first proves the alignment while there is still room to turn something.
