Use with CCV8000 filters which have 1-7/8" UN straight thread ports and use 1-1/2" hoses.
These street elbow fittings seal with an O-ring, and allow the CCV hoses to connect at a 90 degree angle instead of straight into the filter.
(Adapter threads into filter, and then the regular hose barb threads into the adapter.)
Use with hose barb CCV55218.
