Frequently Asked Questions
O-Ring couplings utilize a rubber elastomer seal for high-pressure vacuum tightness, while Flare couplings rely on a metal-to-metal cone seat, often preferred for high-temperature fluid applications.
Yes, they are designed for a wide range of rubber products including brake hoses, power steering hoses, and air conditioning pipes, provided the hose diameter matches the fitting size (#6, #8, etc.).
Iron caps provide additional structural reinforcement for heavy-duty industrial use, while all-aluminum versions offer maximum corrosion resistance and lighter weight for automotive use.
Choose the angle based on the available space between the hose and the port. 90° is ideal for tight corners, 45° for gradual transitions, and Straight for direct linear connections.
UNF stands for Unified National Fine thread. It is a standardized thread series that allows for tighter seals and better vibration resistance compared to coarse threads.
While specifically designed for fluid and air lines, we offer various high-strength joints that can be adapted for sewer cleaning hose systems depending on the pressure requirements.
