Shimano Hydraulic Brake Hose Olive & Connecting Insert Set

Sovereign Hydraulic Sealing: Precision CNC-Machined Brass Compression Armor Meets Airtight Leak-Free Interface Integrity, High-Pressure Safety, and Flawless Hose Splicing

Restore crisp, unyielding lever feedback to your cockpit, eliminate dangerous mineral oil weeping around your master cylinder bar junctions, and complete your internal routing hose trims with total workshop confidence. The Shimano Hydraulic Brake Hose Olive & Connecting Insert Set represents the absolute baseline requirement for hydraulic disc brake servicing—specifically engineered to deliver a crush-deformed, high-pressure structural seal between the brake hose and lever or caliper assembly. Sourcing small technical workshop parts independently from international online warehouses often exposes you to frustrating shipping delays, single-item courier minimums, or unexpected port clearance hold-ups at the border. Epic Sports handles all international logistics natively, straight to Nairobi. Precision-turned from high-grade alloy, this critical hardware ensures absolute braking performance under fire.

Why the Shimano Compression Interface Governs the Lever Line:

• Precision CNC-Machined Solid Brass Compounding: Unyielding structural sealing. The copper-alloy olive ring deforms perfectly flat when compressed by the flange nut, crushing into the outer hose skin to freeze it in place.
• Airtight Zero-Leak Internal Tube Support: Flawless pressure transmission. The heavy-duty steel or brass connecting insert drives cleanly down the core of the hose, completely reinforcing the flexible inner wall against collapsing when clamped.
• Absolute High-Pressure Mineral Oil Defenses: Safety-first engineering. Built to hold a perfect structural interface under extreme internal fluid pressures generated during heavy, high-speed alpine racing blocks or mountain descents.
• Clean Multi-Ecosystem System Variants: Target matched hardware. Stocked in both entry/mid-tier wide-bore layouts (SM-BH59) and premium high-performance narrow-bore configurations (SM-BH90) to match your specific brake family perfectly.
• Mandatory Single-Use Workshop Compression Spares: Critical maintenance insurance. Provides the essential single-use hardware components needed every time you shorten a line, swap a lever, or bleed internal frame routings.

Frequently Asked Questions (FAQ) for High-Performance Mechanics:

Can I mix and match an SM-BH59 insert pin inside an SM-BH90 high-power hydraulic brake hose?

No, this is a critical mistake that can ruin your brakes or cause a sudden crash. While the outer diameters of both hoses match at 5.0mm, the internal tube dimensions are completely different. The standard SM-BH59 hose features a wider internal bore, meaning its gold insert pin has a thick shaft. The premium high-power SM-BH90 hose features a significantly narrower internal bore for increased fluid velocity, requiring a much thinner silver insert pin. If you try to force a thick BH59 pin into a narrow BH90 hose, you will stretch, scar, and split the inner lining, creating a hidden weak point that can catastrophically burst under heavy braking torque. Always match BH59 to BH59, and BH90 to BH90.

Why must I install a completely brand-new olive and insert every time I shorten my brake lines?

Hydraulic olive rings are strictly single-use compression components. When you lock down the internal brake line shroud nut to factory spec, the soft brass olive ring is intentionally crushed and permanently deformed out of shape, biting down tightly into the outer plastic coating of the hose to lock it in place. Once crushed, the metal loses all elasticity. If you pull the hose out to shorten it or route it through a new frame, you can never reuse that compressed olive; attempting to tighten it a second time will fail to form a fresh fluid seal, causing toxic mineral oil leaks and dangerous air ingestion.
