What is a female thread fitting?
What is a female thread fitting?
The terms Male and Female always refer to the threads on the fitting. Male threads are on the outside, like a bolt. Female threads are on the inside, like a nut. The male threads screw into the female threads.
How do I seal BSPP threads?
In low pressure situations extra Teflon tape may be enough to make a seal between two BSPP fittings. In a pinch you can use a pvc tapered fitting where appropri- ate (primarily on cooling jackets.) A tapered female NPT PVC fitting has some give and therefore will thread onto BSPP straight thread.
How are Orfs fittings measured?
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 does flare mean in plumbing?
Flaring allows you to connect tubes to each other or another kind of fitting. Flared ends tend to have an approximately conical shape. The most popular flaring tool for copper tubing is the bar-type tool, which include multiple bits to accommodate different pipe or tube sizes.
Will NPT work with BSPP?
NPT/NPS and BSP threads are not compatible due to the differences in their thread forms, and not just the fact that most sizes have a different pitch.
What size is JIC 8?
JIC 37° Flare (SAE J514)
| Inch size | Dash size | Male Thread O.D. (in) |
|---|---|---|
| 1⁄2 | -8 | 0.75 |
| 5⁄8 | -10 | 0.88 |
| 3⁄4 | -12 | 1.06 |
| 7⁄8 | -14 | 1.19 |
What is the difference between BSP and JIC?
The only difference is Komatsu uses millimeter thread sizes while JIS use a BSP (British Standard Pipe) thread. JIC fitting systems have three components that make a tubing assembly: fitting, flare nut, and sleeve. JIC fittings are commonly used in the Fluid Power industry in a diagnostic and test-point setting.
How tight should an fittings be?
They should be hand tightened and then another 1 or 2 turns, but no more. More turns will put to much pressure on the fitting and may crack it and cause a leak. The Tensile Stress created by tightening the fitting beyond hand tight and 1 or 2 more turns will crack the female fittings.
How tight should hydraulic fittings be?
Once aligned, tighten the nut until it is “firm” against the washer and o-ring, with the nut becoming snug with a feel of metal-on-metal in less than one revolution. Over-tightening causes as many leaks as under-tightening.
What is the thread form of BSPP?
British Standard Pipe (BSPP, BSPF) Thread Form r = Basic Radius = * 137329 p h = Basic Depth of Thread = *640327 p p = Pitch = 1/t.p.i. (Threads per Inch) ISO 228, DIN 259, BS2779, JIS B0202 In Japan this thread is known as (PF) Use prefix G for parallel thread. Example: G1/2
What is the difference between NPT thread and BSPT thread?
Remember that NPT threads have a 60° thread flank angle, and BSPT has a 55° angle (this can be verified with a thread gauge). Although BSP is a foreign thread, it isn’t metric.
What is the thread form of British Standard Pipe?
British Standard Pipe (BSPP, BSPF) Thread Form r = Basic Radius = * 137329 p h = Basic Depth of Thread = *640327 p p = Pitch = 1/t.p.i. (Threads per Inch) ISO 228, DIN 259, BS2779, JIS B0202 In Japan this thread is known as (PF) Use prefix G for parallel thread. Example: G1/2
Can you use a male NPT fitting in a female BSPP?
Male NPT going into Female BSPP In most situations that don’t involve high pressure, a male NPT fitting can be threaded into a female BSPP fitting, using Teflon tape to seal. Note that because the male NPT fitting is tapered it will thread a little farther into the straight threaded BSPP female fitting.
