Our engineers work with your technical team to translate operating conditions into a complete hose specification. The result: fewer failures, longer service life and lower total cost of ownership.
We size hose working pressure to your system relief valve setting - including pressure spikes - so the hose never operates close to its burst margin.
Continuous and extreme temperatures derate working pressure and affect compound choice. We match NBR, HNBR, EPDM and FKM to your real-world operating range.
Abrasion, UV, ozone, chemical splash, MSHA flame resistance - we engineer the cover and reinforcement to the actual field conditions, not catalog averages.
Mineral oil, synthetic fluid, biodegradable oil, water-based, phosphate ester, steam, chemical, food-grade - the inner tube compound is selected for media compatibility and permeation resistance.

Every solution below starts with a customer problem: a hose that fails too often, a circuit that runs too hot, an OEM that needs lower total cost. We engineer the hose construction, cover compound and fitting combination to solve that problem - not the other way around.
Challenge: Boom and arm circuits see continuous cyclic loading with pressure spikes to 1.5× nominal. Standard braided hose fails in 6-12 months.
Solution: High-impulse 4SP/4SH spiral hose rated for 400,000+ impulse cycles. Abrasion-resistant cover, properly crimped to OEM-spec fittings. Service life extended to 24-36 months.
Explore Solution →Challenge: In-plant transfer of oils, chemicals, steam and air often uses the wrong tube compound, causing blistering, permeation leaks and premature replacement.
Solution: Media-matched NBR, EPDM, FKM and chemical-resistant tubes. EN and ISO compatibility documented per application. Cover engineered for the actual plant environment.
Explore Solution →Challenge: Underground and open-pit mining expose hose to abrasion, fire risk, chemical splash and extreme pressure cycles - failure means downtime that costs thousands per hour.
Solution: MSHA-style flame-resistant covers, 4-spiral reinforcement for high-pressure service, abrasion-resistant jackets and proof-tested assemblies crimped to specification.
Explore Solution →Challenge: Equipment manufacturers need a single SKU strategy, drop-in assemblies delivered to the BOM, and consistent quality across container-scale orders.
Solution: OEM-spec hose assemblies delivered crimped, tested, labelled and packaged to your BOM. Custom cover color, brand printing, fitting combination and packaging.

Trusted Worldwide
Distributors, OEMs and equipment manufacturers across three continents specify Quanyi Rubber because every reel is traceable, every batch is tested, and every order ships with the documentation their customers demand.
A hydraulic hose distributor in Germany needed a 2SN supplier with full EN 853 documentation and traceable batch numbers for their Tier-1 customer base. We supplied 40HQ/month with material certificates, impulse test logs and custom packaging for 36 months without a single field failure claim.
A Brazilian construction machinery OEM required 4SP spiral hose assemblies crimped, labelled and packaged to their BOM for direct assembly-line drop-in. We engineered the cover compound for tropical UV resistance and supplied 20,000 assemblies/year with 100%% proof test certification.
A mining equipment dealer in South Africa needed MSHA-style flame-resistant hose for underground longwall systems. We supplied 4SH spiral hose with flame-resistant cover, full impulse certification and a 2-week lead time - against an industry norm of 6-8 weeks.
Every production batch is documented with material certificates, dimensional reports, proof test logs and impulse certification. Full traceability from raw rubber to shipped assembly.

In-House Manufacturing
Controlling every stage from rubber mixing to final pressure test ensures consistent performance across millions of meters shipped.
Internal mixers compound NBR, SBR, EPDM, Neoprene to precise hardness, tensile and oil-resistance targets.
Tubing extruders form the inner tube to tight ID tolerance - the foundation of crimping accuracy.
Braiders and spiral winders apply high-tensile brass-coated steel wire in 1SN, 2SN, 4SP, 4SH and 6SP configurations.
Autoclaves and lead-press lines cure the hose under controlled temperature and pressure for full cross-linking.
Hoses cut to length, fittings crimped to manufacturer-specified diameters, with skiving and labeling.
100%% proof pressure test, sample burst test, and impulse test certification on every production batch.
Quality Assurance
Every hose that leaves our factory has been proof-pressure tested to 2× working pressure. Sample hoses from each batch are burst-tested to verify ≥3× working pressure and impulse-tested up to 400,000 cycles - exceeding SAE J517 and DIN EN 856 requirements. Material certificates, dimensional reports and test certificates are available for every order.
