SHOP TALK // HYDRAULIC BRAKE LINE COUPLER

Worth its weight in convenience, the basic hydraulic brake line connector is a part every shop should have on hand.

This small, lightweight, and practical part is ideal for extending hydraulic brake lines for longtail bike setups (Xtracycle, Surly Big Dummy, etc), cargo bikes, tandems, recumbents, or any other application using standard 5mm outside diameter hydraulic brake lines. Also works great for demo bike fleets or multi-use bikes where the ability to change handlebars without removing internal brake lines is necessary.

The central coupler body itself is machined aluminum with a black anodized finish and is compatible with any industry standard M8 hydraulic compression nut and any associated hose fittings for industry standard 5mm outside diameter hydraulic brake hose.

Hydraulic brake line couplers are available in several different kits to ensure compatibility with the intended braking systems. The central coupler body is universal between all variants; the only differences between kits are the system specific hose fittings.


BASIC / STANDARD MINERAL OIL KITS

Uses a flat bottom brass olive and two-piece hose fitting with a brass barbed insert and mineral oil compatible o-ring.

Intended for use with Shimano, TRP/Gevenalle, Magura, Campagnolo and most other systems utilizing mineral oil.

Due to the different chemical compositions of mineral oil and DOT brake fluid the o-ring seals used in standard mineral oil kits are not compatible with Hayes, Formula, and other systems.

Assembles with Shimano TL-BH62, TRP BR7156, SRAM 00.5315.028.030, or similar hydraulic brake hose fitting tools.


BASIC / STANDARD DOT KITS

Uses a single piece brass olive hose fitting with an integrated barbed insert.

Intended for use with Hayes, Formula, SRAM, and other systems using DOT fluid.

With no o-ring or brake fluid soluble materials this kit is technically compatible with all DOT and mineral oil based hydraulic systems.

Assembles with Shimano TL-BH62, TRP BR7156, SRAM 00.5315.028.030, or similar hydraulic brake hose fitting tools.


BASIC / SRAM COMPATIBLE KITS

Uses a proprietary SRAM Steath-a-majig two-piece threaded aluminum olive hose fitting and threaded stainless steel barbed insert.

Intended for use with SRAM hydraulic systems.

With no o-ring or brake fluid soluble materials this kit may be compatible with other DOT and mineral oil based hydraulic systems.

Assembles with SRAM Handheld Barb Driver Tool (MPN: 00.5315.028.030).
