These aluminum nipples are great for splicing our silicone coolant hose. They are useful when connecting an elbow to a straight section, connecting two elbows, or connecting a reducer to an elbow.
Beads or ridges at each end are large enough to ensure good retention with our Lined Hose Clamps (Part No. 3613-.78, sold separately), but not so large that the hose is difficult to install. Ridge configuration may vary from photo.
