What is a flat face O-ring?
Flat Face O-Ring Hydraulic Fittings use high durometer flat rubber O-rings to effect a gasket like soft seal. The O-ring nests in a special groove machined in the face of the fitting body.
How do you measure a flat face O-ring hydraulic fittings?
The male fittings have the O-ring in a groove in the flat face. MALE: The measurements for the male are taken from the outside of the threads. FEMALE: For Female fittings, the measurement is taken from the inside of the threads.
What is ORFS fitting?
As the name implies, O-ring Face Seal (ORFS) fittings incorporate an O-ring at the face of the fitting and are designed to eliminate leaks in high pressure hydraulic systems.
Is ORS the same as ORFS?
Apr 27, 2020. O-ring face seal is also called ORFS, as per SAE J1453 and ISO 8434-3 standard. ORFS fittings have flat sealing surfaces that contain an embedded seal, which mates to flanged tubing or hose fittings. O-ring boss seal design is also called ORB as per ISO 11926-1 and SAE J1926-1 standard.
What is the difference between JIC and SAE fittings?
JIC fittings are dimensionally identical to AN (Army-Navy) fittings, but are produced to less exacting tolerances and are generally less costly. SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size.
How do I know what size hydraulic fittings I need?
First you should determine the length of a hydraulic fitting by laying it on a table and then stretching your measuring tape across the top of it. Next, determine the outside diameter of the fitting by using your ID/OD calipers.
What is ORSF?
Connection Types: ORFS (O-ring Face Seal) This is known as an elastomeric seal. The seal is created when the o-ring compresses between the o-ring face of the fitting and flat face of the mating ORFS fitting or the formed tube.
Are JIC and UNF the same?
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.
What is female 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.
What thread is ORFS?
ORFS fittings come in straight threads with the outer diameter defined in-dash sizes and the pitch (the distance between each thread, measured in threads per inch or TPI) defined by the UTS (Unified Thread Standard). For example, a -9 –18 ORFS fitting has an outer diameter of 9/16” and 18 threads per inch.
What does JIC stand?
What does JIC stand for? JIC stands for the Joint Industries Council, which first standardized industrial use fittings. These compression couplings have a 37° flared seat on the male and female threaded connections.
What does SAE ORB mean?
SAE Straight Thread 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 EPDM O-ring?
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals.
What type of thread is JIC?
JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 psi) is involved.
