What is an O-ring boss fitting?
An o-ring boss seal is a technique for joining two fluid-carrying pipes, hoses, or tubing. In an o-ring boss (abbreviated ORB) system, a male-threaded part is inserted into a female-threaded part, providing a mechanical seal.

What does Orb stand for in hydraulic fittings?
Connection Types: ORB (O-Ring Boss) ORB, or (SAE Straight Thread O-ring Boss) fittings, incorporate a port connection as recommended by the National Fire Protection Association (N.F.P.A.) for leak prevention in medium and high pressure hydraulic systems.

What is a boss hydraulic fittings?
Boss fittings are plumbing fittings used on o-ring boss systems (ORB), where the male parts are inserted into threaded female parts to provide a mechanical seal.
Do Orb fittings need thread sealant?
No sealant is needed for NPT-F threads, but tape is used for lube. If you like to tighten things a lot get yourself some hydraulic line wrenches, they are stubby and thin and will not let you overtighten lines much.
Is SAE O-ring boss?
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.
Are SAE and ORB the same?
O-Ring Boss: The threads of the SAE straight thread O-Ring Boss (ORB) and the straight thread 37⁰ JIC Flare are the same threads. The difference is the way each thread seals. While the JIC seals on a metal-to-metal flare, the ORB seals on an O-ring, which offers the best leak free connection.
Are JIC and UNF the same?
JIC / SAE 37 degree / UNF Straight. The only effective difference is that JIC (also known as SAE 37 degree) has a conical seating face (37 degree or 74 degree total angle) and UNF Straight has a flat seat – sealing being effected by use of a washer. Male JIC fittings have a convex cone, female fittings a concave cone.
How are orb fittings sized?
NPTF, BSPT and BSPP measure 1/4” larger than their actual size. For example, a 1/4” NPTF, BSPT or BSPP will actually measure 1/2” on the O. D. of the threads. The first number listed is the size of thread, the second number is the threads per inch.
How to measure an O-ring size?
How to Measure O-Rings Place the O-ring on a clean, flat, level surface. Determine the inside diameter by using a ruler to measure from one inner edge to another. Use a ruler to measure the diameter, from one outer corner of the O-ring to the other outer corner. Finally, measure the cross-section. Place the O-ring into a vernier caliper.
What is size O-ring does the Petrel use?
What size o-ring does the Petrel use? The name of the o-ring used is AS568-112. The size of this o-ring is 1/2″ ID by 3/32″ width. This is the same o-ring used in the majority of DIN regulators (not Apeks however).
What are boss fittings?
Boss fittings. Basically, an electrical enclosure or fitting with a “boss” has integral threads, usually five or more. A typical conduit body or FS box are boss type. It must be an integral part of the enclosure; i.e., a hub fitting would not make a Type 12 enclosure a boss enclosure.
What type of lube for O-rings?
O-rings should get a silicone based lubricant. Teflon based lubricants are ok also. My favorites are Magic Lube (teflon and Magic Lube II (silicone) by Aladdin. You can find it at a pool supply store since they are made for pool and spa use.
