Import Banjo Adapter For Ptfe Brake Lines — Buy in wholesale FOB from Supplier in China

The Banjo Adapter for PTFE Brake Lines from Sunny Industry Group Co., Ltd. is a hydraulic brake fitting machined from high-grade forged steel with precision threading to maintain seal integrity under brake system pressure. This adapter bridges PTFE braided brake line and brake caliper or master cylinder ports, with the supplier specifying chromoly steel as an alternative material option for applications demanding higher fatigue resistance. The forged construction method, rather than casting, yields a denser grain structure that resists cracking at the banjo eye under cyclic loading typical of brake pulsation events. Thread engagement length and pitch must match the receiving port specification exactly, as PTFE line systems operate at pressures where minor thread mismatch causes weep leakage.

PTFE (polytetrafluoroethylene) brake line construction consists of a seamless extruded PTFE core, stainless steel braid reinforcement, and an outer PVC or polyester protective layer, with the banjo adapter terminating this assembly at the caliper. The adapter's through-bore allows brake fluid to pass into the caliper while the copper or aluminium crush washer, compressed between adapter face and caliper port, forms the primary seal. Forged steel adapters accept zinc plating or zinc-nickel coating for corrosion protection, though bare steel with a light oil film is common for immediate assembly into coated systems. The 37-degree flared seat variant mates with AN-style fittings common in motorsport, while the flat-faced banjo style suits OEM replacement and commercial vehicle applications where tool access is limited.

Buyers for this component span automotive OEM brake system integrators, aftermarket brake kit manufacturers, motorsport fabricators, and commercial vehicle maintenance suppliers. The adapter supports DOT 3, DOT 4, and DOT 5.1 glycol-based fluids, with material compatibility verified against FMVSS 116 fluid immersion testing. Bulk procurement typically involves lot-based ordering with material test certificates, though exact MOQ and lead time from Sunny Industry Group require direct confirmation. Packaging is generally oil-paper wrapped and bulk-crated for sea freight, with individual polybagging available for retail-channel orders. Importers should specify thread standard (metric M10x1.0 or UNF 3/8-24 are common), banjo eye inner diameter for line passage, and whether the application demands single or double banjo configuration for dual-caliper feed.

Sunny Industry Group Co., Ltd. maintains its registered address at No.26 Haian Road, Sifang, Qingdao, Shandong Province, 266000, China, placing the supplier within Qingdao's established port-industrial corridor with direct access to container shipping terminals. The listing carries a Harbor trust tier designation, which indicates a baseline verification level, though both response rate and average response hours register at zero in the available data. This absence of response metrics means buyers should treat initial contact as untested and allow additional time for quotation turnaround. The company profile does not state year of establishment, employee count, production floor area, or annual revenue figures, so any such claims from third-party sources would require independent verification before reliance.

The supplier's product focus sits within automotive brake system components, specifically hydraulic fittings for PTFE line applications, with the forged steel banjo adapter representing a precision-machined part rather than a commodity casting. No ISO certificates, IATF 16949 automotive quality system registration, or specific OEM approvals are listed in the source data, so buyers requiring TS-16949 traceability must request documentation directly. The address in Shandong province suggests proximity to northern China's automotive component manufacturing belt, though this geographic advantage does not automatically confer logistics capability. Importers should verify whether Sunny Industry Group operates as a manufacturer with in-house forging, or as a trading company coordinating outsourced machining, as this distinction affects quality control protocols and audit requirements.
