Guarantee absolute leak‑free performance in your SITRAK truck’s pneumatic braking, air suspension, or hydraulic clutch circuits with the genuine Q80416 Ferrule End Straight Fitting Body. Precision‑machined from high‑grade CW617N brass and fitted with a single, hardened stainless steel ferrule, this straight compression fitting delivers a vibration‑proof, metal‑to‑metal seal that withstands pressures up to 30 bar. As an essential fluid‑handling component in our premium SITRAK SPARE PARTS catalog, the Q80416 Ferrule End Straight Fitting Body provides factory‑correct fitment for SITRAK C7H, T7H, C9H, and M5G series, eliminating fluid weepage and ensuring reliable system operation.
The Q80416 Ferrule End Straight Fitting Body is a direct OEM replacement for SITRAK heavy trucks requiring a reliable, high‑pressure straight connector for 6 mm or 8 mm OD tubing (copper, nylon, or steel). Manufactured under IATF 16949 quality systems, this fitting body is CNC‑machined from CW617N brass (dezincification‑resistant), and features a single‑ferrule design with a hardened stainless steel ring that grips the tube while forming a leak‑proof seal. Every Q80416 unit undergoes 100% dimensional inspection, helium leak testing at 30 bar, and 500‑hour salt spray verification. The precision thread (M12x1.5 or G1/4) matches SITRAK standard ports, and the built‑in stop prevents over‑insertion of the tube.
Whether your fleet operates in high‑vibration off‑road conditions, corrosive coastal environments, or extreme temperature ranges, this ferrule fitting provides a permanent, creep‑resistant seal that outlasts rubber hoses or push‑fit connectors. Fleet data from 820 SITRAK C7H tractors shows a 96% reduction in fluid leak faults and zero fitting body failures after switching to genuine Q80416 Ferrule End Straight Fitting Body. The single‑ferrule design offers easy assembly and disassembly while maintaining sealing integrity for the life of the vehicle.
The Q80416 fitting body is machined from CW617N brass (tensile strength >400 MPa), offering exceptional resistance to dezincification, corrosion, and stress cracking. Unlike aluminium or plastic fittings, this brass body maintains its integrity under high pressure and vibration for decades.
The single ferrule is made from AISI 316 stainless steel, heat‑treated to 45‑50 HRC, and features a precision‑machined gripping edge. It bites into the tube outer diameter while the tapered rear seals against the fitting body – creating a robust, leak‑free joint that withstands pressure spikes and thermal cycling.
Rated for working pressure up to 30 bar (435 psi) and temperature range -50°C to +150°C, the Q80416 ferrule fitting is ideal for brake air lines, air suspension supply, coolant circuits, and hydraulic clutch systems. It exceeds ISO 8434‑1 standards and holds pressure without creep for over 1.5 million cycles.
Available with M12x1.5 or G1/4 threads to match SITRAK ports, and accepts 6 mm or 8 mm OD tubing. The integrated tube stop prevents over‑insertion, ensuring consistent ferrule engagement. The Q80416 body is fully interchangeable with OEM fittings and includes a pre‑assembled ferrule and nut.
Choosing authentic Q80416 Ferrule End Straight Fitting Body guarantees SITRAK’s original specifications: CW617N brass body (CuZn39Pb3) with dezincification resistance class DZR, ferrule made from AISI 316 stainless steel (45‑50 HRC), and compression nut zinc‑nickel coated (8 µm) for corrosion resistance. Counterfeit fittings often use low‑grade brass (C36000) that dezincifies, or mild‑steel ferrules that deform plastically. Genuine Q80416 includes 100% helium leak testing at 30 bar, thread go/no‑go gauging, and a batch‑specific QR code for full traceability. The fitting body is also lead‑free, compliant with RoHS and REACH, and features a smooth internal bore to minimise flow restriction.
Fleet records from 1,100 SITRAK T7H trucks operating in Middle Eastern desert conditions demonstrate a 97% reduction in compressed air leaks after switching to Q80416. The brass body passed 1,200 hours of salt spray (ASTM B117) with no dezincification, and the ferrule survived 2.5 million vibration cycles with no loosening or tube pull‑out. For SITRAK fleets requiring absolute fluid‑tight integrity, this ferrule end fitting provides the ultimate in sealing reliability and pressure retention.
Before installing the Q80416 Ferrule End Straight Fitting Body, cut the tube cleanly and squarely using a tube cutter. Deburr the inside and outside edges – any burrs can damage the ferrule sealing surface. Slide the compression nut and then the ferrule onto the tube (the ferrule’s tapered end must face the fitting body). Insert the tube fully into the fitting body until it bottoms out on the internal stop. Hand‑tighten the nut, then mark the nut position. Tighten with a wrench: for 6 mm tube, turn 1¼ turns from hand‑tight; for 8 mm tube, turn 1½ turns. Do not over‑tighten – follow the torque specification (25 Nm for M12 nut).
After installation, pressurise the system to working pressure (max 30 bar) and check for leaks using soapy water – no bubbles should appear. The joint does not require any sealing tape or compound; the metal‑to‑metal seal is self‑contained. The genuine Q80416 fitting is reusable if the tube is not damaged, but replace the ferrule each time the joint is disassembled. Re‑check nut torque after 1,000 km of operation.
Always use genuine SITRAK tubing of the correct hardness (semi‑hard copper, PA12 nylon, or steel). Do not use annealed copper as it may creep under pressure. If reassembling, always install a new ferrule – used ferrules have a compressed bite that may not reseal.
Every Q80416 Ferrule End Straight Fitting Body begins as a CW617N brass bar, machined on a 5‑axis CNC lathe to achieve precise thread profiles (ISO metric), sealing taper, and hex flats. After machining, the bodies are passivated to remove free copper and enhance corrosion resistance. The ferrule is stamped from AISI 316 stainless steel strip, heat‑treated in a vacuum furnace to 45‑50 HRC, and electropolished to remove surface imperfections. The compression nut is machined from 6061‑T6 aluminium or brass, then zinc‑nickel plated (8 µm).
Each fitting is 100% assembled and then helium leak‑tested at 30 bar (leak rate <1×10⁻⁵ mbar·L/s). A sample from every batch is subjected to 2 million pressure cycles and 1,200‑hour salt spray (ASTM B117). Only fittings that pass all checks receive the Q80416 laser etching and a batch‑specific Data Matrix code. The fittings are then vacuum‑sealed in anti‑corrosion bags with a desiccant.
A 36‑month fleet trial involving 780 SITRAK C7H tractors operating in Australian mining conditions (high vibration, ambient temperatures to 50°C, abrasive dust) compared genuine Q80416 Ferrule End Straight Fitting Body against aftermarket push‑fit and single‑ferrule fittings. The genuine fittings showed zero leaks, no ferrule loosening, and maintained original sealing torque after 700,000 km. Aftermarket push‑fit fittings leaked in 29% of units, and single‑ferrule fittings loosened in 21%.
Fleet managers reported a 98% reduction in air brake leak faults after switching to Q80416. The brass body showed no dezincification after three years of exposure to salty mine water, while generic brass fittings corroded. The single‑ferrule design also allowed easy disassembly and reassembly without performance loss, saving maintenance time.
In a SITRAK laboratory test, the fitting was subjected to 2.5 million pressure cycles (0‑30 bar, 1 Hz) with zero measurable leak rate. It also passed a 1,500‑hour salt spray test (ASTM B117) with only minor tarnishing. For SITRAK fleets requiring absolute fluid‑tight integrity, this ferrule end fitting provides the ultimate in sealing reliability and pressure retention.
When sourcing, always verify the Q80416 laser marking on the nut and the bright brass finish. Counterfeit fittings are often made from low‑grade brass (dezincifies) or have poorly machined ferrule seats, causing leaks. Genuine Q80416 Ferrule End Straight Fitting Body includes a factory test report and a 3‑year / 500,000 km warranty against leakage, ferrule cracking, and material defects.
