15611 NPT Male

SST machinery provides 15611 NPT male hose fitting, the size range is from 3/16" to 2", the material of the fitting is steel Q235, the treatment of the fitting is good quality of white zinc plating.

NPT is short for National pipe taper, which is a U.S. standard for tapered threads, widely used on pipes and fittings for over 100 years. This connections seal pipes for fluid and gas transfer. They are available in iron and brass for low-pressure applications and carbon steel or stainless steel for higher pressure. The nominal pipe size can be identified by physically measuring the thread diameter.  

NPT connections rely on thread deformation- a metal to metal sealing design where the threads of the connectors themselves form together. This design is ideal fore single assembly applications and not recommended where connections will be assembled and disassembled frequently due to wear on the threads from deformation. 

The packaging way for 15611 NPT male hose fitting is mass packaging, we will put our fitting into plastic bag, then put them into boxes, then package the boxes into plywood pallet, so there will be no problem for delivering our bolts by sea, and you can move the pallet easily by forklift, the pallet is around 1CBM.

With over 10 years of experience in transmission design and manufacturing, SST machinery enjoys a good reputation among its customers and exported its goods to EU, USA, south American, ASIA etc.

WHAT ARE THE MOST COMMON FITTING TYPES?

The most common types of fittings are listed below, along with a brief description of each:

• NPT/NPTF – the most commonly used type of thread in North America, these are recognizable by the tapered inner diameter and the tapered outer diameter, making the fitting self-sealing.

• BSPT (JIS-PT) – commonly known as the British Thread Type, these are standard fittings which have been internationally adopted for sealing pipe ends and making connections.

• Metric Taper – the most commonly used thread type in Europe, it is well known for its precise cylindrical inner and outer diameters.

• SAE Straight Thread – a very reliable and reusable thread type, these have excellent sealing because of the 90-durometer O-Rings.

• ISO 6149 – has a metric straight thread O-Ring port, which is very useful for diagnostic port applications.

• JIS-B2351 – largely used as hose adapters for equipment designed in Japan or Korea, these usually have BSP threads

• DIN Metric – DIN is the German Industrial Standard, and these are popular throughout Germany and much of Europe

• BSPP (JIS-PF) – JIS stands for Japanese Industrial Standards, and these BSPP connectors follow the standard British thread dimensions

• 4-Bolt Flange – there are a number of different types of 4-bolt flange options, either for normal duty or heavy duty
