The genuine OEM 803190339 Hose Clamp is a precision-engineered hydraulic hose retainer designed specifically for XCMG motor graders. This essential component secures hydraulic hoses to the chassis, preventing chafing, twisting, and vibration-induced wear in GR series graders.
Manufactured to original equipment specifications, the 803190339 hose clamp is made from spring-grade stainless steel with a protective rubber cushion. It provides secure clamping force from 0.5 to 2.5 kN, accommodating hose diameters from 12 mm to 32 mm, and operates reliably from -40°C to +120°C.
Using genuine XCMG 803190339 hose clamps eliminates hose movement, abrasion damage, and premature hose failure. Each clamp undergoes 100% spring force testing and corrosion resistance validation before packaging. Upgrade your grader’s hose routing reliability with authentic OEM quality.
The 803190339 hose clamp features a spring-band design that automatically adjusts to hose thermal expansion and contraction. This maintains constant clamping force without crushing the hose inner tube, unlike rigid clamps that cause localized stress.
The integrated EPDM rubber cushion isolates the hose from metal edges, preventing abrasion even under high vibration. The cushion has a Shore A hardness of 65, providing optimal grip without damaging the hose outer cover. It resists oil, ozone, and weathering.
The stainless steel band is pre-tensioned during manufacturing to deliver a consistent clamping force across the entire circumference. The worm-drive mechanism allows fine adjustment without tools. Each 803190339 clamp is designed for single-bolt mounting to the grader frame.
This hose clamp directly replaces OEM part 803190339 on XCMG GR2153, GR200, GR180, GR3005, and GR3505 graders. It is used to secure steering hoses, brake lines, and implement hoses along the frame, axle, and articulation joints.
For older GR135 and GR165 series, the 803190339 clamp offers drop-in compatibility with existing mounting brackets. Cross-reference with aftermarket numbers: HC-2210, XCMG-HC310. Standardizing on genuine clamps ensures consistent clamping force and eliminates hose movement.
Typical installation points include the front frame crossmember, rear axle housing, and hydraulic tank mounting plate. The clamp can also be used in pairs for long hose runs requiring support every 500 mm.
Before installing the 803190339 hose clamp, clean the mounting surface and ensure the hose is free of dirt. Open the clamp fully, position it around the hose, and insert the mounting bolt through the hole. Torque the mounting bolt to 6-8 Nm. Do not overtighten.
Ensure the rubber cushion fully surrounds the hose. The clamp should allow slight axial movement of the hose (approx. 1-2 mm) to accommodate thermal expansion but prevent lateral chafing. After installation, flex the hose to verify secure retention.
All 803190339 hose clamps are manufactured in XCMG’s ISO 9001:2015 and IATF 16949 certified facilities. Each batch undergoes 100% spring force testing at 20°C and 80°C, plus corrosion resistance testing (720-hour salt spray).
Random samples are subjected to vibration testing per SAE J1455 (10-500 Hz, 5g acceleration) with no loosening or wear. The rubber cushion is tested for oil immersion (IRM 903, 70h at 100°C) with volume swell < 15%. XCMG provides a 12-month warranty.
Aftermarket hose clamps often use low-grade carbon steel that rusts quickly, or rubber cushions that harden and crack. Genuine 803190339 clamps use stainless steel and EPDM rubber, validated by thousands of field hours.
Fleet operators report that genuine XCMG clamps eliminate hose abrasion failures entirely, while aftermarket clamps often cause hose damage within 1,000 hours. Protect your hydraulic hoses from premature wear and costly leaks. Choose safety, choose reliability, choose 803190339.
The 803190339 hose clamp is stocked in XCMG regional warehouses across North America, Europe, Asia-Pacific, the Middle East, and Africa. Standard lead time is 3-5 working days. Express freight available. Bulk orders (500+ pieces) receive volume discounts.
Each clamp is packed in anti-static bags to prevent contamination. Technical datasheets and installation guides are provided. XCMG parts specialists offer remote support for hose routing optimization.
A large infrastructure contractor in Australia replaced all aftermarket hose clamps on 18 XCMG GR215 graders with genuine 803190339 clamps. After 6,000 operating hours, zero hose abrasion failures were recorded, reducing hydraulic oil leaks by 90%.
In Canadian mining operations at -40°C, the 803190339 clamp maintained clamping force without cracking, while aftermarket clamps became brittle and failed. Operators reported no hose movement or chafing even under extreme vibration.
The 803190339 is available as a single clamp or in bulk packs (10, 50, 100 pieces). Custom cushion materials (Viton® for high-temperature, HNBR for high-abrasion) can be ordered with a 10-day lead time. Minimum order for custom is 50 pieces.
For fleet managers, XCMG offers hose clamp kits that include all required clamps for a complete grader hydraulic system. Kits come with color-coded labels for easy identification. Contact our parts team for consignment stock arrangements.
To maximize service life of your 803190339 hose clamp, inspect annually for rust or rubber cracking. Replace if the rubber cushion shows hardness or cracking. Re-torque mounting bolts after the first 500 operating hours.
If a hose is replaced, always install a new 803190339 clamp – the rubber cushion may have taken a permanent set. Genuine XCMG clamps typically provide 10,000+ hours of reliable service under normal conditions. Store spare clamps away from ozone and UV light.
In summary, OEM number 803190339 represents the industry standard for XCMG motor grader hose retention. From material selection to spring force accuracy, every detail meets the highest durability requirements. Never risk hose abrasion or failure. Order the genuine 803190339 hose clamp for your fleet today and experience the XCMG quality difference.
With proven reliability in thousands of graders worldwide, the 803190339 clamp continues to outperform generic alternatives. Ensure maximum hose life, zero chafing, and extended component protection. Choose genuine XCMG for your grader’s hose routing system. Secure your fleet’s uptime with OEM authenticity.
