Choosing a DTE Sewer Jetting Hose: Medium, Dimensions and Operating Conditions

1. Start with the medium and the application

The published application for this sewer jetting hose is drain and sewer cleaning, heavy-duty high-pressure water cleaning, and use in high-pressure sewer cleaning. Its construction matches water service:

The product description also lists oil resistance, abrasion resistance and tensile resistance. The materials do not say that the hose may convey oil, chemicals, solvents or hot media. Treat it as a water jetting hose. For any other medium, ask for written confirmation first.

2. Match the dimensions to your jetter and fittings

Four sizes are published. Pick the inner diameter that matches your pump flow and nozzle setup. Check the outer diameter against hose reels, guides and fittings.

Hose lengths, end fittings and coupling types are not part of the published specification. Do not assume this sewer jetting hose pipe comes as a ready-to-use assembly. Confirm length, fittings and any assembly work when you request a quote.

3. Check pressure against your equipment

All four sizes share a working pressure of 3625 psi (250 bar) and a burst pressure of 9063 psi (625 bar). When choosing:

• Your jetter's maximum operating pressure, including pressure peaks, should stay at or below the 250 bar working pressure.
• Never treat the burst pressure as a usable operating limit. It is a failure value, not a rating for normal work.
• If your unit runs above 250 bar, this hose does not fit the job.

4. Allow for bend radius in the field

Bend radius grows with size, from 70 cm for 1/2 to 130 cm for 1-1/4. If you route the hose through manholes, tight access points or onto reels, check that the layout respects the published bend radius for the size you choose. A larger bore can raise flow capacity, but it needs more room to bend.

5. Confirm the operating temperature

The published temperature range is -40°C to 82°C (-40°F to 180°F). The product description also notes good flexibility in low-temperature environments, which matters for winter sewer maintenance. For water or ambient conditions outside this range, the hose does not apply.

When this hose is not the right choice

• Your jetter's operating pressure is above 250 bar (3625 psi).
• The medium or environment falls outside -40°C to 82°C.
• You need to convey oils, chemicals or other non-water media and have no written confirmation.
• You need a bore outside the four published sizes, or a complete kit with fittings and accessories that has not been confirmed.
• Your procurement requires specific certifications, brand equivalence or test reports.

Buyer checklist before requesting a quote

1. Medium: clean water for sewer and drain jetting.
2. Size: 1/2, 3/4, 1 or 1-1/4, matched to your pump and nozzles.
3. Pressure: equipment maximum at or below 250 bar.
4. Routing: published bend radius achievable on site.
5. Temperature: within -40°C to 82°C.
6. Commercial details: length, fittings, pricing, lead time and any documents you need, all confirmed in writing with Hebei Qiruite Rubber and Plastic Products Co.,Ltd.

If your requirements pass these checks, the Sewer cleaning hose (sewer cleaning & jetting hose) is a documented option for high-pressure sewer and drain water jetting.
