HOPE COPPER HOSE WASHER X 10

When shortening hydraulic lines, swapping calipers, or moving a premium braking system between frames, achieving a flawless, pressure-tight seal is paramount. The Hope Copper Hose Washer X 10 pack delivers factory-spec reliability directly to your home workshop or professional bike shop. Engineered specifically to interface between the brass shroud insert and the main connector fittings of Hope's high-performance hydraulic systems, these genuine UK-manufactured copper washers act as the critical barrier keeping highly corrosive DOT brake fluids securely inside your lines.

Because copper is a malleable metal, these washers are designed to permanently crush and conform precisely around microscopic imperfections between mating surfaces when torqued down. This structural malleability creates a complete, airtight seal that prevents pressure loss, spongy lever feel, and fluid migration onto your brake pads. While reusing old washers frequently causes persistent slow leaks, this convenient 10-pack ensures you always have a fresh, ductile sealing surface ready to go whenever you trim a hose or perform system maintenance across your mountain bike fleet.

Key Features

• Genuine Hope Spare Parts: Engineered to exact original factory specifications (Part Number: HBSP161) for flawless compatibility with premium Hope disc brake lines.

• Malleable Copper Construction: High-purity copper deforms perfectly under initial torque to create a 100% leakproof, permanent mechanical seal.

• DOT Fluid Compatibility: Chemically optimized to withstand long-term exposure to aggressive DOT 4 and DOT 5.1 high-performance hydraulic braking mediums.

• Essential Rebuild Hardware: Critical replacement components for shortening lines, refreshing connector barbs, or running fresh internal cable routing.

• Convenient 10-Piece Workshop Pack: Provides a generous supply of individual washers to completely service multiple bikes or stock up a workshop drawer.

Specifications

✅ Why This IS For You

• ✅ The Proactive Home Mechanic: You regularly bleed, trim, or swap hydraulic lines and understand that using a fresh crush washer is mandatory to prevent slow fluid leaks.

• ✅ Hope Brake System Enthusiasts: You want absolute peace of mind by using genuine UK factory spares instead of generic, off-the-shelf industrial washers.

• ✅ Multi-Bike Classrooms & Garages: You manage several bikes equipped with Hope stoppers and want a multi-pack so you are never caught out mid-build.

• ✅ Riders chasing a crisp bite point: You are rebuilding a soft lever system and want to ensure every seal at the banjo and lever interface is perfect.

❌ Why This May NOT Be For You

• ❌ Mineral Oil System Users: While copper works structurally, these specific dimensions are tuned for Hope layouts; check your specs if trying to adapt to Shimano or Magura lines.

• ❌ Riders Expecting a Full Fitting Kit: This product contains sealing washers only; it does not include the essential brass olives (HBSP159) or inserts (HBSP160) needed for a full hose trim.

• ❌ One-Off Quick Fixes: If you only need to fix a single brake lineset once every five years, a bulk 10-pack might leave you with more spare hardware than you require.

BFC PRO TIP

Copper hose washers are strictly single-use items. Once they have been torqued down, they undergo a mechanical process called "work hardening," which permanently compresses the metal and ruins its ability to reshape itself a second time. If you try to save a dollar by reusing an old washer on a new hose build, it will almost certainly weep fluid and contaminate your brake pads. When tightening your hose connector nut over a fresh washer, use a steady hand and torque it precisely to spec—over-tightening will over-crush the copper, distorting the internal brass barb and restricting vital fluid flow!
