Key Product Advantages
- Space Saving: Integrated male and female end design replaces the combined assembly of elbow and nipple.
- Reliable Sealing: Tapered NPT thread allows dry sealing performance; better tightness with PTFE tape or thread sealant.
- Multiple Material Options: Corrosion-resistant brass, high-temperature and high-pressure resistant stainless steel, and high-strength forged steel.
- Strict Precision Control: Threads inspected by go/no-go gauges for every batch, with 2.5 times rated pressure hydrostatic pressure testing.
Typical Application Scenarios
- Instrument air piping: The 1/8 npt 45 degree street elbow for pressure gauge adaptation and connection
- Pneumatic tool branch lines: The 1/4 inch 45 degree street elbow to save cabinet internal space
- Bypass connection of water treatment equipment: The outdoor applied 1/2 npt 45 degree street elbow in stainless steel
- Hydraulic systems and lubrication oil pipelines
FAQ
A: A standard elbow plus nipple combination contains two threaded connection points with higher leakage risks. The integrated structure of 45 degree street elbow removes one joint connection, greatly reducing leakage hazards and avoiding installation misalignment caused by length tolerance of short pipes. Under vibration working conditions, the integrated structure delivers over 30% longer fatigue resistance service life.
A: First, confirm the basic size according to pipe nominal diameter: 1/8 inch is commonly used for instrument sampling and analysis pipelines with approx. 6mm outer diameter tubing; 1/4 inch is the universal size for pneumatic tools and small mechanical equipment; 1/2 inch fits main and branch lines for water, oil and low-pressure steam delivery.
Secondly, select materials based on media: brass for water and compressed air, stainless steel for corrosive or high-temperature fluid. In addition, confirm thread standards — NPT is American standard tapered pipe thread and cannot be interchanged with BSPT. You are recommended to provide the maximum working pressure and temperature of your system, and our team will offer professional selection guidance and material certificates.
