Hydraulic Straight Nipple
Double-threaded through-bored straight hydraulic nipple.
Manufacturing Scope
Hydraulic Straight Nipple is a Fittings family precision-turned on a Goodway SW-20, covering 9 variants — diameters ⌀9.2–19.6 mm, lengths 21–41 mm, standard material Steel (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.
The family is machined from ⌀20 mm bar stock; its longest variant is RAKB-NPL-11 at 41 mm. Besides turning, the family requires thread turning (7 sizes from M5 to M12x1.5), hex flat milling (AF 8–17) and axial drilling (⌀2.5–8 mm). All of it is completed in a single setup, without the part leaving the machine.
The variant with the highest length-to-diameter ratio is RAKB-NPL-04: 21 mm long at ⌀9.2 mm, L/D 2.3. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to 6g tolerance; the smallest is RAKB-NPL-04 (⌀9.2 mm) and the largest RAKB-NPL-11 (⌀19.6 mm). The family includes threaded, hex-drive, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
