Great quality
Less expensive than the local speed shop, seals great and was able to run my -6 hose cleanly.

Fits absolutely perfect on my vett filter
After having to send Jegs brand fittings back that fit horrible it was such a relief to get these that fit my vett filter absolutely perfect! Would give 10 stars if I could.
