Manufacturer of aluminum Half couplings in China. Material from 6061-T6 ,5083-O
Our Aluminum Half couplings are made from high quality raw material,thread conform to ASME B1.20.1 and meet or exceed SCH 40 wall thickness for 150# rating. Couplin can be used Aluminum Female Weld On Bung, Weldable Fuel Tank Fitting
Pipe coupling is a one of most common thread pipe fittings,it is with one end or both ends female thread (Normally NPT thread) to connect the Pipes
NPT Fitting Sizes are based on the “PIPE” that would typically thread into these couplings.
It’s important to understand that both the Male and Female NPT fitting has a 1.8 DEG taper applied to the thread. This taper is intended to create an interference fit once threaded together. It is expected that the male mating fitting will not thread all the way down. Sufficient tightness is created approx 1 turn or less past hand tight, any further and you risk damaging the fitting. To get a liquid tight seal you will need to use thread sealant that is appropriate for your application.
NPT Half Couplings are tapered threaded fitting on one end and the other end weldable on tanks.
Half couplings are NPT fittings that contain female NPT fittings on one end.
Our Half coupling size are in 1/4″, 1/2″, 3/4″, 1″, 1.5″, 2″ 2 1/2″ 3″ 4″ 6″ 8″ NPT sizes.

Aluminium alloy 6061 is a medium to high strength heat-treatable alloy with a strength higher than 6005A. It has very good corrosion resistance and very good weldability although reduced strength in the weld zone. It has medium fatigue strength.
Aluminum 6061 is a precipitation-hardened alloy, meaning it is strengthened during a heat treatment process that involves the disbursement of particles within the metal’s grain structure, hindering motion and effectively increasing strength and durability. Among its major alloying elements are silicon and magnesium, in addition to elements such as iron, copper, and zinc. Developed in 1935, aluminum 6061 is one of the most versatile aluminum alloy options. This is because it is able to be fabricated by many of the techniques most often used, offering great workability and range of mechanical properties. Further, 6061 exhibits a high level of corrosion resistance, and is highly weldable. Aluminum 6061 is available in numerous versions including tempered 6061-T6 and 6061-T651 grades, as well as pre-tempered 6061-O grade.
