Manufacturing Scope

Fittings are connectors that join two elements in pneumatic, hydraulic and fluid lines without leaking. In this category we produce 133 types across 14 part families: push-in fitting bodies, quick-connect male ends, air-line nipples, blanking plugs, straight fitting nipples, banjo fitting bolts, barbed hose tails, hydraulic straight nipples, reducing nipples, banjo bolts, tapered fitting ends, compression fittings, bulkhead (panel-pass) unions and knurled push-fit nipples. We machine steel, stainless steel, brass and aluminium; on sealing faces and threads we typically hold ±0.01 mm to h6/H7 class. Every part is turned in a single operation on the Goodway SW-20 Swiss lathe across a ⌀7–19.6 mm range (machine ceiling ⌀20 mm), so complex geometries — threads, hex wrench flats, knurls and tapered seats — come off the machine finished. Beyond the 133 catalog types, we also make custom sizes to your drawing. The process is simple: send a technical drawing or sample and receive a quote by material and quantity.

Threading defines this category: 133 of the 133 variants (100%) carry a thread. The full operation mix is 133× thread turning, 131× hex flat milling, 113× axial bore, 51× taper turning, 19× knurling, all of it completed in one setup on parts 10–49 mm long.

Everything here is held to a single tolerance class (6g), and 100% of the variants map to a DIN or ISO standard. The highest length-to-diameter ratio in the category belongs to RAKA-QCP-06L at L/D 2.9 — this category is made of short, rigid bodies, where diameter tolerance rather than deflection decides the result.

Every part is CNC-turned to your drawing — series, small batches and custom turned parts. Send your drawing (PDF/DWG/STEP) for a quote.

Parts are CNC-turned on a Goodway SW-20 Swiss lathe. Bar stock is fed continuously, and threads, hex wrench flats, knurls, tapered seats and through-bores are machined in a single set-up. This delivers repeatable tolerances and consistent surface quality across production runs.
