Running -04 hose on a low pressure hydraulic setup and need something that'll connect to a 1/2-20 flareless tube without a bunch of fuss. This the right fitting for that?
Answer by: Customer Support on Aug 18, 2025, 8:22 AM
For a -04 hose connecting to a 1/2-20 flareless tube, this is a solid match. It uses a straight configuration with an Ermeto 7000 series flareless tube end, so it seats securely without requiring a flared connection. The TTC series is rated for general purpose low and medium pressure hydraulic work, which fits right in line with what you're describing. One thing worth knowing is that if your system is subject to shock loads or pressure spikes, pairing it with H277 or H435 hose is the recommended approach for that application.
