The HOPE HBSP158:2 hydraulic connector fitting is an essential spare part to ensure a watertight and reliable connection between 6mm aviation hydraulic hoses and HOPE braking components. Manufactured in the United Kingdom at the historic Barnoldswick factory, this 2-groove connecting nut is specifically designed for 6mm diameter steel braided aviation hoses that equipped HOPE systems before October 2017.

Technical highlights

• Specific compatibility: Designed exclusively for 6mm outer diameter braided aviation hoses supplied by HOPE before October 2017. Not suitable for standard 5mm hoses.
• Identification by grooves: The 2 grooves (2 lines) allow immediate identification of compatibility with 6mm braided hoses, as opposed to the standard HBSP158 (1 groove) for 5mm hoses.
• Stainless steel construction: Machined from high-quality stainless steel ensuring corrosion resistance, durability and performance retention in all conditions.
• Featherweight: At only 2 grams, this fitting does not add weight to your braking system while ensuring robust attachment.
• British HOPE manufacturing: Made in the United Kingdom according to the strict standards of Hope Technology, pioneering brand in MTB hydraulic braking since 1989.

Application and compatible systems

This connector fitting is used for installation or maintenance of HOPE hydraulic braking systems. It is compatible with all HOPE calipers and levers from 2004 onwards, notably the Tech, Tech Evo, Mono, Moto, Mini, E4, V4, X2, RX4 series and other models equipped with 6mm aviation hoses. The nut combines with an olive (HBSP159), an insert (HBSP160) and sealing washers to form a complete and safe hydraulic connection.

Usage specifications

• HBSP158 vs HBSP158:2 distinction: The standard HBSP158 (1 groove) is intended for 5mm black hoses and 5mm aviation hoses. The HBSP158:2 (2 grooves) is reserved for 6mm braided aviation hoses from before October 2017.
• Diameter verification: Before ordering, check the outer diameter of your hose. If you are using a 5mm hose or a recent hose (post-2017), opt for the standard HBSP158.
• Mineral oil compatibility: HOPE systems absolutely require the use of HOPE mineral oil to preserve seal integrity and guarantee braking performance.
