Trim Pump Fittings with -5 ORB (O-Ring Boss) pump-side connections by Buckshot Racing #77 are precision-machined for reliable, leak-proof performance in medium to high-pressure hydraulic systems.
 
Engineered specifically for hydraulic trim pump systems, these marine hydraulic fittings are built to handle the demands of high-performance boats, offshore race craft, and other harsh marine environments where durability and consistency are critical.
 
On the pump side, each fitting uses a -5 ORB (O-Ring Boss) connection with 1/2"-20 straight threads. The ORB interface combines straight threads with an O-ring to create a positive, leak-proof seal into the pump body. This design is widely regarded as one of the most dependable sealing methods for hydraulic circuits, especially in applications with high pressure and continuous vibration.
 
On the hose or trim line side, the fittings are available in common JIC inverted flare configurations, allowing them to integrate cleanly with standard hydraulic trim hoses and marine hydraulic lines.
 
Options include:
Female -3 JIC (3/8"-24 threads)
Female -4 JIC (7/16"-24 threads)
Male -4 JIC (7/16"-24 threads) Compare to Hardin Marine and CP Performance 
 
These JIC flare connections create a metal-to-metal seal at the flare seat, delivering strong, repeatable sealing performance under load and helping to maintain leak-free hydraulic connections in demanding environments.
 
All trim pump bases and fittings in this system are designed as a matched package. The pump-side ORB seal provides a secure, O-ring-backed seal into the pump, while the hose-side JIC flare compresses against the female flare seat. Together, they offer excellent resistance to vibration, thermal cycling, and pressure spikes—conditions that are routine in high-performance marine and offshore racing applications.
 
In real-world use, Buckshot Racing #77 Trim Pump Fittings excel in hydraulic trim pump systems, including Mercury Racing–style setups, as well as other medium to high-pressure hydraulic circuits on performance boats.
 
They are well-suited to recreational performance boating, competitive outboard boat racing, and offshore racing applications where a secure, leak-free hydraulic connection can make the difference between a winning pass and an early return to the dock.
