“ The Pride and Joy of the Craftsman ” — 工匠的骄傲与喜悦
Over 12 years of precision engineering in high-grade rubber, TPEE, and polyurethane sealing solutions. Trusted globally for heavy-duty commercial vehicles and specialized construction machinery.
Engineering Excellence
Xingtai Kale Machinery Parts Co., Ltd. (CALEPH) is a leading manufacturer specializing in high-performance automotive sealing solutions, engine overhaul components, and heavy-duty chassis boots. By using raw material formulations consisting of NBR, Fluororubber (FKM), Polyurethane (PU), and custom thermoplastic elastomer ether ester (TPEE), we ensure our products perform under the harshest working conditions.
Our state-of-the-art production facility incorporates custom mold tooling and automated vulcanization to guarantee tight manufacturing tolerances. Every single seal, boot, and filter is engineered to extend the reliability and service lifespan of commercial trucks, excavators, and passenger vehicles.

CALEPH premium oil seals are engineered to protect mechanical bearings and rotating shafts. Available in both standard continuous and advanced **Split Oil Seal** layouts for rapid installation without machine disassembly.
CALEPH precision-molded O-Rings are engineered for static and dynamic fluid sealing. They prevent vacuum loss, hydraulic leaks, and environmental intrusion in automotive, pneumatic, and chemical systems.
Specifically designed for excavators, loaders, and bulldozers. This highly professional maintenance and repair kit series provides complete sealing elements that withstand heavy impact, abrasion, and intense fluid pressure.
Engineered for underground coal mining machinery and heavy-duty hydraulic roof support cylinders. CALEPH mining support seals offer exceptional wear resistance, extrusion resistance, and hydrolytic stability under extreme operating conditions.
CALEPH precision engine cylinder head and exhaust gaskets deliver exceptional sealing recovery and durability. Our multi-layer steel (MLS) and composite gaskets prevent hot gas leaks, coolant intrusion, and oil pressure loss.
Manufactured to exactly match standard OE shapes and dimensional requirements. Highly resistant to engine oil, synthetic oil formulas, and extreme high heat, keeping the top of the engine clean and leak-free.
Molded using advanced **TPEE (Thermoplastic Polyester Elastomer)** and chemical-resistant rubber. Our boots protect universal joints and steering components from mud, water, dust, and debris.
Complete all-in-one engine rebuild and overhaul sealing series. Includes cylinder gaskets, crankshaft seals, valve stem seals, oil pan gaskets, intake manifold gaskets, and ancillary O-rings to ensure a complete maintenance job.
High-precision rebuild kits for hydraulic steering gear assemblies, gearboxes, and fluid oil pumps. Eliminates hydraulic fluid leakage and restores responsive steering.
CALEPH professional air, oil, and cabin filters are built to protect engines and components from particulate wear, ensuring optimal airflow and lubricating fluid purity.
