Question by: Dale G on Sep 20, 2025, 7:53 AM
got a tight spot on a brass run, what exactly is this fitting and what threads are on it?
Answer by: Customer Support on Sep 21, 2025, 9:57 PM
For tight hydraulic connections layouts, it gives you a 45 degree change in direction using a street elbow layout, meaning one end is male and the other is female. Both ends are NPTF threads to SAE J476, sized 1/4-18.

Can this elbow handle regular hydraulic pressures without issue?
Answer by: Customer Support on Apr 26, 2025, 2:32 PM
This elbow, constructed from straight brass, offers good resistance against corrosion and wear under standard hydraulic conditions.
Question by: Glen P on May 29, 2025, 7:41 PM
both ends on this thing are 1/4-18 NPTF right, or is one end a different size?
Answer by: Customer Support on May 30, 2025, 8:30 PM
Both ends are the same size, 1/4-18, and both are NPTF thread type. One end is male and the other is female, which is what makes it a street elbow rather than a standard elbow. That male-to-female configuration lets you thread it directly into a fitting or port without needing a separate coupling in between.
