Triple-Lok 2 combines the versatility of stainless steel Triple-Lok with the added advantage of an elastomeric seal. Triple-Lok 2 incorporates a replaceable seal in the nose of the flare, which is positioned so that leak-free connections are made without compromising the strength of the fitting. Triple-Lok 2 is a direct interchange for any industrial 37° flare fitting, allowing current 37° flare fitting users to take advantage of Triple-Lok 2 without changing hoses or tubes.
