Specifications apply only to the hose. The potential working pressure may be lower than specified above for hose lines with
couplings due to the nominal pressure of the couplings or the type of assembly.
Quality Control
As a professional manufacturer of engineering-grade hoses, product quality remains Sunmoon's foremost priority. Consequently, we employ a comprehensive suite of testing methods to ensure that our hoses deliver flawless quality assurance in real-world engineering applications. Listed below are the various testing methods we utilize for our hose products:
Working Pressure Test 4 hours per hose at 260m pressure test line
Abrasion Resistance Test Performance benchmarking for every shift in resin hardness (PVC/TPU) or material formulation.
Bursting Pressure Test Mandatory verification for every raw material batch and new process protocol.
Cover Adhesion Test Systematic bond-strength comparison and verification for every production lot.
Anti Static Test Test every oil hose to match the anti-static standard - Resistance: Max 4.9 Ohm/m (Rated); 0.98 Ohm/m (Measured under working pressure).
Customized Services at SUNMOON
At SUNMOON, we don’t just supply standard hoses—we build application-based layflat hose solutions for different working conditions. With years of manufacturing experience in TPU and NBR layflat hose, we understand that every project has different requirements for diameter, pressure, length, reinforcement, cover thickness, and fittings.
That’s why we offer flexible customization based on your actual use scenario, helping you get the right hose for frac water transfer, manure drag systems, dewatering, mining, municipal bypass, and other demanding applications. The result is better performance, longer service life, and a more practical fit for your jobsite.
