The 3/4" x 3/4" Female Adapter FPT has
one end that is threaded to fit on a 3/4" filter piece. The opposite end of the
Adapter FPT is narrow and is meant to have a 3/4" tube slide over it and fit
tightly. If a tighter seal is wanted then the use of hose clamps or ratchet
clips would be advised.
2 1/2" L x 1 1/4" W (at larger end) and 3/4" W (at narrow end)
