Original SANY Venting Pipe Assembly 61000726 Construction Machinery Parts

The genuine SANY parts reference 61000726 is the Venting Pipe Assembly, a pre‑formed tube that equalizes pressure between a fluid reservoir and the atmosphere in SANY hydraulic and fuel systems. The 61000726 venting pipe assembly incorporates a flame‑arrestor fitting and a dust‑resistant cap, preventing contamination while allowing the tank to breathe during thermal expansion and contraction.

Manufactured from zinc‑nickel plated steel tubing with crimped rubber hoses and clamps, this assembly resists corrosion and fatigue. Each 61000726 unit is 100% pressure‑tested and dimensionally verified for SRT dump trucks, SY excavators, SW wheel loaders, and motor graders.

Material and Design of Venting Pipe Assembly 61000726

The venting pipe assembly 61000726 consists of a seamless steel tube (8 mm OD, 6 mm ID) bent to a specific shape, a flame‑arrestor fitting (brass with stainless steel mesh), and a flexible rubber hose section (EPDM, 12 mm ID) with spring clamps. The steel tube is zinc‑nickel plated (8-12 µm) to resist corrosion. The assembly total length is 450 mm ±5 mm.

The flame‑arrestor fitting is crimped to one end of the steel tube. It contains a sintered metal disc (50 µm porosity) that stops sparks from propagating into the fuel or hydraulic tank while allowing air to pass freely. The other end of the steel tube connects to an EPDM hose via a barbed fitting and two constant‑tension clamps. The hose is terminated with a plastic elbow and a dust cap with a labyrinth seal.

The assembly is designed to mount on the tank’s vent port (M16 x 1.5 thread). The rubber hose section allows slight misalignment and dampens vibration. The dust cap prevents dirt and water ingress but opens under slight positive pressure (0.02 bar) to release built‑up pressure. The flame‑arrestor meets ISO 10069‑1 requirements for off‑road equipment.

All 61000726 assemblies are 100% air‑tested at 0.5 bar for 30 seconds with no leakage. The flame‑arrestor is tested for flow restriction (pressure drop < 50 mbar at 100 L/min). A laser‑etched batch code on the steel tube provides full traceability to the tube lot, bending program, and crimping data.

Critical Applications of Venting Pipe Assembly 61000726

The venting pipe assembly 61000726 is installed on hydraulic oil tanks, fuel tanks, and coolant expansion tanks in SANY equipment. It allows air to enter the tank as fluid is drawn out (preventing vacuum collapse) and allows air to escape as fluid expands due to heat (preventing over‑pressurization). Without a proper vent, tanks can deform, seals can leak, or pumps can cavitate.

On SRT dump trucks, this venting pipe is used on the hydraulic tank and the fuel tank. On SY excavators, it is installed on the swing drive housing breather and the hydraulic tank. The flame‑arrestor feature is critical in fuel systems to prevent a flashback from igniting vapors. The dust cap protects the tank from contamination during normal operation.

A clogged venting pipe (due to mud, ice, or paint) will cause the tank to collapse or bulge. Symptoms include a distorted tank shape, oil leakage from seals, or pump noise due to cavitation. Inspect the vent regularly and replace if damaged. Always use genuine SANY venting pipe assemblies.

Compatible SANY Models & Interchange Information

The venting pipe assembly 61000726 is used across SANY’s heavy equipment line: SRT45, SRT55, SRT95, SRT115 dump trucks; SY215 to SY500H excavators; SW305, SW405, SW465 wheel loaders; SMG200/220 graders; and STC crawler cranes. It is also fitted on SANY concrete pump trucks, reach stackers, and generator sets.

The assembly fits a tank vent port with M16 x 1.5 threads. The rubber hose connection is for a 12 mm OD barb. Always verify the original venting pipe configuration (length, bend angles, and end fittings). When ordering, specify 61000726 to receive the correct tube length, flame‑arrestor type, and dust cap.

For fleet maintenance, stock genuine 61000726 assemblies. Aftermarket vent pipes may lack the flame‑arrestor or use inferior rubber that cracks, allowing dirt ingress. Genuine SANY venting pipes guarantee correct flame‑arrestor performance, dust protection, and dimensional accuracy.

Proper Installation of Venting Pipe Assembly 61000726

Before installing the venting pipe assembly 61000726, inspect the tank vent port for thread damage and ensure it is clean. Apply a small amount of thread sealant (Loctite 567) to the M16 male thread, but keep it away from the flame‑arrestor disc. Hand‑tighten the fitting, then torque to 25 Nm using a 19 mm wrench. Do not over‑tighten.

Route the rubber hose away from hot surfaces (exhaust manifold) and moving parts. Secure the hose using the provided spring clamps. Ensure the dust cap is oriented upward to prevent water ingress. The cap should open freely when you blow gently into the pipe – if not, replace the cap. The flame‑arrestor fitting must be vertical or within 15° of vertical to function correctly.

After installation, run the engine and check for any vacuum or pressure buildup in the tank (the tank should not suck in when cold or bulge when hot). If the cap is missing or damaged, replace the entire assembly – the cap is not sold separately. Store spare assemblies in a clean, dry place away from UV light.

Symptoms of a Failed Venting Pipe Assembly 61000726

A failed 61000726 venting pipe assembly typically shows signs of tank deformation: a dented (collapsed) hydraulic tank or a swollen (bulging) fuel tank. You may also hear a hissing sound when opening the filler cap (vacuum release). Oil leaks from tank seams or seals can occur due to excess pressure. Pump noise (cavitation) may be present.

If the flame‑arrestor is clogged with dirt or paint, the tank may not vent at all. If the dust cap is missing or damaged, dirt can enter the tank, contaminating the fluid and damaging pumps and valves. A cracked rubber hose will also allow dirt ingress and may cause a fuel leak (if on a fuel tank).

During preventive maintenance, inspect the vent for blockage by removing the dust cap and blowing through the pipe – it should pass air freely (little resistance). Check the rubber hose for cracks or hardening. Replace the assembly if any abnormality is found. Use only genuine SANY venting pipe assemblies.

Quality Assurance & Full Traceability for 61000726

Every venting pipe assembly 61000726 is manufactured in an IATF 16949 certified facility. The steel tube is tested for tensile strength and zinc‑nickel coating thickness. The flame‑arrestor disc is validated for porosity and flow restriction. Each assembly is 100% leak‑tested at 0.5 bar and visually inspected for correct crimping and clamp placement.

A sample from each batch is subjected to thermal cycle testing (-40°C to +120°C, 100 cycles) with no leakage or cracking. The rubber hose is tested for oil immersion swelling (≤15% after 70h at 100°C). The flame‑arrestor is tested for spark arrest performance (no flame propagation). A laser‑etched batch code on the steel tube provides traceability to tube lot, bending program, and assembly date.

For bulk orders, SANY provides a Certificate of Conformance (CoC) confirming that all 61000726 assemblies meet material, dimensional, and performance specifications. Regular third‑party audits ensure compliance with ISO 9001:2015 and IATF 16949. Use only genuine SANY venting pipes for guaranteed tank protection.

Field Performance of Genuine SANY Venting Pipe Assembly

Field data from SANY equipment operating in Australian mines and Brazilian sugar cane fields shows that genuine 61000726 venting pipe assemblies last over 12,000 hours without clogging or cracking. The zinc‑nickel steel tube resists rust, the flame‑arrestor remains unblocked, and the EPDM hose maintains flexibility. Dust caps effectively keep out mud and dust.

Aftermarket vent pipes often use plain steel tubes that rust internally, blocking airflow. Their rubber hoses may be made of low‑grade PVC that hardens and cracks within 2,000 hours. The flame‑arrestor may be missing or ineffective, posing a fire hazard. Genuine SANY venting pipes eliminate these risks. Fleet owners report 95% fewer tank deformation issues after switching to genuine venting pipes.

To maximize service life, inspect the vent at every oil change (500 hours). Blow through the pipe to check for blockage. Replace the assembly every 8,000 hours as preventive maintenance. Keep the dust cap clean. Following these practices ensures proper tank breathing and prevents fluid contamination.
