Our aluminum nipples are designed for splicing together 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. This 2" long splicing nipple fits inside any of our 32mm (1 1/4") ID silicone hoses.
Beads or ridges on the outside at each end are large enough to ensure good retention when used with our Lined Hose Clamps (Part No. 3613-1.75, sold separately) but not so aggressive as to cause cuts in the hose. Ridge configuration may vary from photo.
