1/4" thru 1/2" can be rated as high as 15,000 psi
3/4" thru 1" can be rated as high as 10,000 psi
Anything larger would only be rated no higher then 5000 psi.
..... But the type of material/wall thickness will directly effect the working pressure ratings

Why square threads are used in a screw jack?
§ Screw threads have better compression strength than other threads. § Due to low thread angle there is no radial pressure on nut. § Due to smaller angle, the lead of screw is less.
What are PG threads?
* World-wide most commonly used type thread * Characterized by its major diameter and its pitch * Designated by the letter M followed by the value of the nominal diameter and the pitch, both expressed in millimetres and separated by the multiplication sign '×' * NPT Thread = National Pipe Thread* Taper rate for all NPT threads is 1/16* The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, as opposed to straight thread fittings* PG Thread = Panzer-Gewinde (also Panzer-Rohr-Gewinde) * German thread type * Depth of thread smaller than NPT or Metric, but larger flank angle Part Number Index sorted By Thread Types & Sizes: Metric Threads NPT Threads PG Threads ---- TORQUE RECOMMENDATIONS FOR STRAIN RELIEF FITTINGSTorque in inlb (Nm)METAL STRAIN RELIEF FITTINGS PLASTIC STRAIN RELIEF FITTINGS DOME NUTS THREAD AND LOCK NUTS DOME NUTS THREAD AND LOCK NUTS PG 7, M12x1.5 36.9 (4.17) 55.3 (6.25) 14.4 (1.62) 22.1 (2.50) PG 9, PG 11, M16, PG 13.5, 3/8" NPT, 1/2" NPT, M16x1.5, M20x1.5 36.9 (4.17) 55.3 (6.25) 22.1 (2.50) 33.2 (3.75) PG 16, 1/2"NPT-E 44.2 (5.00) 66.4 (7.50) 29.5 (3.33) 44.2 (5.00) PG 21, PG 29, PG 36, PG 42, PG 48, 3/4"NPT, 1"NPT, 1-1/4"NPT, 1-1/2"NPT, M25x1.5, M32x1.5, M40x1.5, M50x1.5, M63x1.5 59.0 (6.67) 88.5 (10.00) 44.2 (5.00) 66.4 (7.50)Note: Torque for dome nuts was determined using a metal rod. It may vary for cable, depending on the crush resistance of the cable. We recommend to determine the actual torque empirically, testing the actual cable used. The values shown above are for reference only. Note: Nylon strain relief fittings installed in a threaded connection and exposed to elevated temperature should be retained with a sealant such as Locktite® to avoid a loose connection when temperature fluctuates. ---- Nema RatingsIP Ratings ---- provides cable products at competitive prices with exemplary customer service.

Would a screw with more or less threads make work easier?
It is easier. The question is not complete enough to be answered. The word EASIER needs to be further defined. so the question should read: What is easier to [add information here]; more screw threads or less screw threads?
What is the difference between class 150 and DIN 16?
DIN 16 : max working Pressure is 16 bar Class 150 : max working pressure 21 bar
What is difference between design pressure and working pressure?
The working pressure is also referred to as the Maximum Operating Pressure (MOP). The MOP is the highest pressure expected during operation. The Maximum Design Pressure (MDP) includes the maximum pressure that is protected by relief valves in case of failure. For example, if the MOP is 100 psi and their are relief valves set at 10% above the MOP the MDP would be 110 psi.
Are NPT pipe threads compatible with NPSM threads?
No, NPT threads are not compatible with NPSM threads. A pipe with NPT threads tapers slightly, while an NPSM-threaded pipe does not taper.
What a npt valve is in a water tank pressure system?
npt, national pipe thread, is a standard for threads on a screw. I (not a plumber) don't believe "npt valve" makes sense , but probably refers to a valve which has npt threading. Yes, a NPT Valve would be a valve with pipe threads as opposed to a sweat valve which has solder connections. There are several other type of piping connections too.
What is full form of NPT threads?
national pipe thread
What is the difference between pipe threads and bolt threads?
NPT = pipe Briggs standard = Pipe NFT and NFC and ASAE = bolt
What is the difference between BSPT and NPT?
Thread angle is different (55° vs 60°).NPT threads are flattened at the peaks and valleys, while BSPT threads are rounded.Threads per inch (TPI) is different for two (except for a couple of cases).
What npt pipe threads full name?
National Pipe Threads or the Briggs Standard NFT = National fine threads NCT National corse threads ASAE America society of auto engineer threads etc
What is a standard pipe thread?
Called Briggs Standard AKA NPT and the other threads NOT normally used in plumbing is NFT and ASE threads
What is the size or measurement of a standard paintball air source adapter?
if you are talking about the threads they are 1/2" NPT
How can you fit a oil pressure sending on a 1995 5.0 ford racing engine if you have a sending unit that only lights a light but the new pressure sending unit for a gauge dont fit because of clearance?
You can go to your local auto shop or most hardware stores and look for a brass extension. most American oil pressure sending units usually have 1/8 npt or 1/4 npt threads.
What does Npt mean in plumbing?
In regards to pipes and tubing, NPT stands for national pipe thread. NPT is the American standard for threaded pipes and fittings regarding the tapered threads.
What is NPT X NPT?
NPT x NPT= (NPT)2 or N2P2T2
American Standard Pipe threads Has anyone ever called it out as an ASPT 2.00?
no its just called ASPT or NPT= National Pipe thread
