Ask A Question

Description & Features

The 12MP-08FP reducer bushing by Brennan Industries Inc features a robust design engineered for high-pressure applications. This bushing is constructed from straight steel, ensuring durability and reliability under maximum dynamic pressure of up to 5,000 psi.

The component has an overall length of 1.170 mm and meets SAE J476 specification standards for its threads. The male NPTF thread on connection B1 measures 3/4-14, while the female NPTF thread on connection B2 measures 1/2-14. The precise thread drills are 0.719 mm for B1 and 0.531 mm for B2, guaranteeing a secure fit and optimal performance.

Ideal for industrial environments where stringent specifications are required, this reducer bushing facilitates seamless connections and minimizes leakage risks. The series 5406 ensures compatibility and ease of integration with other hydraulic components.

Question by: Earl T on Jul 8, 2025, 9:30 PM
what's the pressure rating on this reducer bushing? running a pretty demanding hydraulic circuit and need to know it'll hold up
Answer by: Customer Support on Jul 10, 2025, 5:56 PM
5,000 psi max dynamic pressure is what this bushing is rated for. Straight steel construction, so it's built to handle real working loads without backing down. For most industrial hydraulic circuits, that rating gives you plenty of headroom.

got a 3/4-14 nptf port but my hose end is 1/2-14 nptf, is this the bushing that steps it down?
Answer by: Customer Support on Dec 15, 2025, 2:24 PM
It’s a reducer bushing with a 3/4-14 male NPTF on one side (B1) and a 1/2-14 female NPTF on the other (B2), so it’s meant to adapt a 3/4-14 NPTF female port down to accept a 1/2-14 NPTF male fitting.
