Is SAE same as Orb?
This fitting is also known as O-Ring Boss (ORB) The seal take place by compressing the O-ring in the chamfer. The threads hold the connection mechanically. Commonly known as “SAE”, this port is very common on hydraulic pumps and cylinders.
What are straight pipe threads used for?
Straight Pipe Threads in Pipe Couplings, NPSC They are used to form pressuretight joints when assembled with an ANSI Standard external taper pipe thread and made up with lubricant or sealant.
What is straight thread o-ring?
As the name implies, these O-Rings are used to seal Straight Threaded Tube Fittings. As with other O-Rings in static application designs, they make a seal between two mating components. Unlike most O-Rings, they are not completely housed in a rectangular groove or gland.
What are straight threads called?
However, NPT threads are tapered and NPS threads are straight (parallel). Both threads have a 60° included angle and have flat peaks and valleys.
Does NPT need o-ring?
Pipe fittings, which use tapered thread, don’t use O-rings, but rather must use compounds or teflon tape to help seal the threads. National pipe thread taper (NPT) is a U.S. standard for tapered threads used on threaded pipes and fittings.
What is O-ring boss thread?
SAE Straight Thread O-ring or O-Ring Boss (ORB) is a multipurpose thread ideal for medium and high-pressure hydraulic applications. The male thread contains an o-ring at the base which mates with a chamfer machined into the female counterpoint, which makes this thread type ideal for non-leak applications.
Does NPT need O-ring?
Does an fittings need Teflon tape?
Don’t use Teflon tape, Teflon paste or pipe dope. Do use a sealant. Teflon tape, Teflon paste and pipe dope is intended for metal pipe and fittings. Plastic fittings do not need this lubrication.
Which is hydraulic fitting has straight thread and O-ring?
Recommended by the NFPA for optimal leakage control in medium and high pressure hydraulic systems. The male fitting has a straight thread and O-ring. The female port has a straight thread, a machined surface (minimum spotface) and a chamfer to accept the O-ring.
Which is SAE fitting has straight thread and O ring?
SAE J1926-1 This fitting is also known as O-Ring Boss (ORB) Recommended by the NFPA for optimal leakage control in medium and high pressure hydraulic systems. The male fitting has a straight thread and O-ring.
What kind of fittings do I need for an O ring boss?
O-ring Boss fittings are an excellent choice for medium to high pressure applications. Our O-ring Boss thread fittings and adapters are equivalent to fittings from Parker Hydraulics, Eaton Aeroquip, Weatherhead, Goodyear, and Gate Hydraulics.
How does a straight thread on a hydraulic pump work?
The female port has a straight thread, a machined surface (minimum spotface) and a chamfer to accept the O-ring. The seal take place by compressing the O-ring in the chamfer. The threads hold the connection mechanically. Commonly known as “SAE”, this port is very common on hydraulic pumps and cylinders.
