BRENNAN ORFS X MALE BSPP 3/4

Description & Features

Manufactured by Brennan Industries, this straight steel hydraulic adapter connects a 1-3/16-12 male face seal O-ring (ORFS) thread to a 3/4-14 male BSPP end, making it a practical solution for joining SAE J1453-compliant face seal circuits to British Standard parallel thread ports. The ORFS X Male BSPP 3/4 is part of Brennan's FS7709-ED series and features an ED captive seal design on the BSPP end, which retains the O-ring during installation and helps ensure a reliable, leak-resistant connection.

The NBR O-ring seal material offers solid resistance to petroleum-based hydraulic fluids, making this fitting well suited for mobile equipment, industrial machinery, and other hydraulic systems where mixed-standard connections are required. Straight construction keeps the assembly compact where space or routing constraints are a factor. California residents should note this product is subject to Proposition 65 requirements.

What exactly does "ED captive seal" mean?
Answer by: Customer Support on Nov 27, 2025, 3:49 PM
That refers to the design on the BSPP end, where the O-ring is held in place during installation. This helps prevent leaks by keeping the O-ring properly seated.
