Earl's Swivel-Seal Hose Ends may be used with Perform-O-Flex, Auto-Flex or Ruff-Stuff stainless braided hoses. The Swivel-Seal has a cutter style end, used for over 40 years in the aerospace industry, and 20 years in automotive competition. During assembly of cutter style fittings, the end cuts into the hose, creating a tight, leak proof seal. The finest design of hose ends available, Earl's Swivel-Seal hose ends feature adjustability, for indexing purposes, after attachment to the hose. This unique line of hose ends has been developed to allow the hose end to be threaded directly into a female port without the bulk and complication of an adapter fitting. In all cases the coupler can be rotated independently of the hose end, this allows the coupler to be threaded into the part while the hose and hose end are held stationary. Both step-up and step-down coupler sizes are available.Pit Stop USA offers Earl's Swivel Seal 90° Male AN Thread Hose End -10 AN Hose to 7/8-14 (-10 An) 849010 at low everyday prices.
