Our most popular hydraulic sealing solutions trusted by Sydney-based contractors, equipment dealers, and industrial operators across New South Wales.
Sydney and the broader New South Wales region represent one of Australia's most active markets for hydraulic components. From the Hunter Valley coalfields to Port Botany's freight terminals and the Western Sydney construction corridor, hydraulic systems are the backbone of daily operations.
NSW accounts for over 40% of Australia's coal output. Hydraulic cylinder seals are critical in longwall mining machinery, roof supports, and haul trucks operating in demanding underground and open-cut environments.
Sydney's multi-billion-dollar infrastructure pipeline — including the Sydney Metro, WestConnex tunnels, and Western Sydney Airport — drives enormous demand for excavator seals, crane cylinder kits, and heavy plant hydraulic components.
From the Hawkesbury River farms to the Central West grain belt, tractors, harvesters, and irrigation systems rely on durable double-acting piston seals that resist UV exposure, dust ingress, and temperature cycling.
Port Botany handles millions of tonnes of freight annually. Reach stackers, ship loaders, and container handling equipment all depend on high-pressure hydraulic seals for continuous, leak-free operation.
Sydney Airport and NSW's expanding high-speed rail network require precision-grade sealing solutions that meet stringent safety standards — a core capability of Kelong's certified product range.
Wind turbine pitch and yaw hydraulic systems demand long-life, low-friction seals. As NSW accelerates its renewable energy transition, demand for specialist hydraulic sealing is growing rapidly.
Shaanxi Kelong New Material Technology Co., Ltd. was established in 1996. It is a high-tech enterprise integrating R&D, production and sales. The main products are combined sealing products, High Pressure Hydraulic Hose and Longwall Chock Haulers. Products are primarily applied in coal mining and metal mining, and are also widely used in civil aviation, high-speed railway, wind power, and other fields.
The sealing products adopt the equipment and production technology of DMH Company in Austria. Our hydraulic hose production base uses a complete set of equipment imported from Italy, with an annual output of more than 15 million metres of various hydraulic hoses. Our total annual output value exceeds 58 million USD, and we hold ISO system and IRIS certificates.

With over 400 employees — including nearly 180 engineers and technicians — and R&D personnel accounting for 17.5% of total staff, Kelong holds a dominant position in the domestic market with an 8% product market share. High-pressure rubber hoses and frame-type handling vehicles are projected to enter the domestic top three within two years.
The hydraulic sealing industry is evolving rapidly. Here are the key trends driving demand for advanced cylinder seals across Sydney and NSW.
Polyurethane (PU) and PTFE compounds are replacing traditional rubber in high-cycle applications. These materials offer superior abrasion resistance, wider temperature tolerance (−40°C to +200°C), and longer service intervals — reducing total cost of ownership for Sydney fleet operators.
Modern hydraulic systems increasingly incorporate pressure sensors and IoT monitoring. Precision-machined seals with tighter tolerances are essential to prevent micro-leakage that can distort sensor readings — a growing requirement among Sydney's smart construction sites.
Australian environmental regulations are tightening around hydraulic fluid spills, particularly near waterways and heritage sites. High-performance seals that eliminate leakage are no longer optional — they're a compliance requirement for NSW operators.
As equipment manufacturers in Sydney and Asia-Pacific move toward proprietary cylinder designs, demand for custom-profiled seals — including compact piston kits, asymmetric rod seals, and multi-piece seal assemblies — is accelerating. Kelong's in-house R&D centre supports full OEM/ODM capability.
Sydney importers are increasingly sourcing directly from certified Chinese manufacturers to bypass distributor margins. With ISO-certified quality, competitive ex-works pricing, and reliable logistics to Australian ports, Kelong is positioned as a preferred direct-supply partner.
Electric excavators and hybrid construction machines are entering the Sydney market. These platforms use electrohydraulic actuators that demand ultra-low-friction seals — a specialty area where Kelong's PTFE and composite seal lines excel.

Our sealing products are manufactured using the precision equipment and proven production technology licensed from DMH Company in Austria — one of Europe's foremost specialists in hydraulic sealing systems. This ensures every seal meets exacting dimensional tolerances and material consistency standards demanded by Australian OEM customers and aftermarket suppliers.

Our hydraulic hose production base operates a complete set of equipment imported from Italy — the global benchmark for flexible hose manufacturing. With an annual output exceeding 15 million metres, we supply high-pressure hose assemblies to complement our seal product range, offering Sydney customers a one-stop hydraulic component solution.
