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 35mm (1 3/8") 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. 3613-2.25, sold separately) but not so aggressive as to cause cuts in the hose. Ridge configuration may vary from photo.
Simply slip one hose over one end of the nipple, leaving about half of the joiner exposed. Slip the other hose over the other end until the two hoses meet in the middle. Add hose clamps for a secure, leak-free connection!
