Q: Are these "ISO 7241-A" or "ISO 7241-B" couplers?
A: The TL74 is an ISO 7241-B coupler. It is vital to note that ISO 7241-A and ISO 7241-B are not interchangeable. You must verify that your machine’s ports match the B-series specification.
Q: What is the benefit of the 3/8" SAE thread on a 1/4" body?
A: This configuration allows you to adapt a 1/4" body coupler system to 3/8" SAE hydraulic lines. SAE threads provide a reliable, leak-proof seal commonly used in high-pressure hydraulic circuits.
Q: Can these be connected under full system pressure?
A: Standard ISO 7241-B poppet couplers are not designed for connection under full system pressure. Always depressurize your hydraulic lines before connecting or disconnecting to ensure safety and prevent damage to the internal seals.
Q: Why is the dust cap important?
A: Keeping your hydraulic system clean is essential to preventing premature component failure. The included dust caps block dirt, moisture, and debris from entering the coupler face, which protects the internal valve and extends the life of your hydraulic circuit.
