Classic nipples but with reducing port. Nipple is an element with two male threads on both sides with, in this particular case, different sizes. Reducing nipple can come in handy, whenever dealing with pneumatic installation, to connect other elements with different size internal threads. Our reducing nipples are made of nickel-plated brass, can work in temperatures ranging from -20°C to 150°C and can easily withstand pressure even up to 16 bar.
