The TEE-THREAD BRANCH 1/4 X 1/8 is a highly practical product designed for use with nylon or copper air brake tubing. It is DOT compliant and meets SAE J246 requirements. With its all brass construction and pipe thread sealant, this fitting offers numerous benefits. It provides a no-leak assembly instantly, saving both time and expense. Unlike tape shredding or liquid sealant washout, it will not contaminate systems. Additionally, it can be reused up to five times and provides excellent thread lubrication to prevent galling. Sold individually, it fits most makes and models.
