MLRSN1405 — Rotating Sewer Nozzle, 1/4″ Connection, #05 Orifice
- The AR MLRSN1405 is a compact, self-rotating sewer nozzle engineered for professional jetting crews
who need consistent wall-to-wall cleaning in small and mid-size lines. - Equipped with a 1/4″ female threaded inlet and a precision #05 orifice, it is tuned
for smaller jetter hose sizes commonly used on service trucks, trailers, and portable jetting units. - A water-driven internal rotor converts pressure into continuous 360° rotation, delivering steady,
controlled scrubbing of the entire pipe circumference. - Its hydraulic balance provides smooth forward thrust, reduced vibration, and reliable navigation through bends,
offsets, and transitions. - Built from corrosion-resistant stainless steel, the MLRSN1405 is designed for daily-duty performance in wastewater,
grease, and light chemical environments.
Key Features & Performance
- #05 orifice sizing is calibrated to balance jet impact, water consumption, and thrust for typical
small-hose jetter outputs. - Rotating jet pattern produces a continuous 360° cleaning envelope, scrubbing away grease, biofilm,
soap, and soft mineral deposits. - Rear-facing jets create controlled back-thrust that pulls the nozzle steadily down the line without excessive recoil
or operator fatigue. - Optimized jet geometry helps break up deposits and flush debris downstream, reducing the chance of reformation and
repeat blockages. - Compact body is well suited for residential laterals, small commercial drains, and tight access points.
Construction & Internal Design
- Stainless steel body provides resistance to corrosion, abrasion, and chemical exposure in sewer and
drain service. - Precision-machined internal rotor and bearing surfaces are engineered for smooth rotation and consistent torque
transfer from the jet stream. - 1/4″ female threaded inlet connects directly to standard small-bore jetting hose assemblies
used on light and mid-size rigs. - Compact, balanced profile reduces drag and improves tracking through bends, reducing the risk of hang-ups at fittings
and transitions. - Jet orifices are drilled to maintain predictable flow and spray geometry over long service intervals.
How the Rotating Jet System Works
- Pressurized water enters the nozzle and is routed through angled jets that generate both cleaning impact
and rotational force. - The angled jets drive an internal rotor, spinning the head to sweep the jet streams around the pipe circumference.
- As the nozzle advances, rotating jets carve a uniform cleaning path, removing grease, soap, soft scale, and suspended
solids from the pipe wall. - Rearward jets create thrust that pulls the nozzle forward, carrying loosened debris toward the downstream recovery
point or manhole. - The result is a combined cutting and flushing action that outperforms static tips in many
maintenance and troubleshooting scenarios.

Benefits & Operational Advantages
- Full wall coverage: rotating jets help prevent streaking and untreated sections commonly left by
fixed patterns. - Balanced thrust and control: hydraulic design keeps motion stable so operators can work more safely
and efficiently. - Improved productivity: can clean lines faster and more completely than basic fan-spray tips in
typical maintenance work. - Reduced callbacks: more thorough wall cleaning lowers the likelihood of rapid re-accumulation of
deposits. - Compact format: ideal for service trucks and portable rigs that specialize in smaller lines and
confined access.
Industries & Typical Applications
- Residential service: house laterals, kitchen lines, bathroom stacks, and floor drains.
- Light commercial: restaurants, food prep areas, retail facilities, and small institutional sites.
- Municipal maintenance: smaller-diameter laterals and service connections feeding larger mains.
- Industrial support: light process drains with soaps, oils, and suspended solids.
- Contractor fleets: drain-cleaning specialists and plumbing contractors using 1/4″ hose rigs.
Compatibility & System Integration
- Designed for jetter systems using 1/4″ hose assemblies with flow and pressure matched to the #05
orifice. - Compatible with many truck-mounted, trailer, and cart-based jetters configured for small-bore drain work.
- Works best when paired with appropriate filtration to keep grit and hard particles from entering the nozzle body.
- Should be matched to pump GPM and operating pressure according to jetter manufacturer and orifice charts.
- Suitable for integration with reels, guides, and safety equipment used in professional high-pressure jetting.
Setup, Use & Maintenance
- Attach the MLRSN1405 securely to a 1/4″ hose fitting using thread sealant rated for high-pressure water service.
- Start at reduced pressure to verify rotation and flow, then bring the system up to working PSI.
- Feed and retrieve the hose in a controlled manner to ensure full wall coverage and protect fittings from shock loads.
- After each job, flush the nozzle with clean water to clear fines and prevent partial blockage of the orifice.
- Inspect jet openings, threads, and the exterior regularly; replace worn parts or retire the nozzle if performance
drops significantly. - Store dry in a protective compartment to prevent accidental impact damage and contamination of the jet orifices.
MLRSN1405 What’s Included & Best Practices
- Included: AR MLRSN1405 rotating sewer nozzle with 1/4″ female inlet and #05 orifice.
- Documentation: reference setup and safety information from AR or your WSHPWR.com system guide for
correct orifice sizing and operating pressures. - Best practice: always confirm nozzle orifice sizing against pump GPM to maintain safe backpressure
and effective cleaning performance. - For heavy root intrusion or hard, mineralized scale, use this nozzle as part of a tooling package
that may also include mechanical cutters or specialty heads.
