Keep your internally routed frame neat, quiet, and completely shielded from the elements. The Jagwire 5mm Housing Angled Entry Frame Plug is a premium workshop-grade solution engineered for modern bicycles with internal cable routing setups. When routing premium 5mm hydraulic brake hoses or heavy-duty mechanical housings through your frame, open ports can leave unappealing gaps that let in dirt and moisture. This specialized grommet slides straight over your outer housing to cleanly bridge the gap, providing a factory-fresh finish.
Crafted from a highly durable, automotive-grade EPDM rubber compound, this plug is precision-molded to press-fit firmly into standard 8.0mm round frame entry and exit ports. Because it features an integrated, tight-tolerance 5mm central channel with a clever angled pathway, it allows the housing to exit the frame tube at a natural, stress-free trajectory, completely eliminating harsh kinks. This tight interface creates an effective barrier against water ingress during wet winter commutes, muddy trail rides, or routine bike washing, significantly extending the life of your internal components.
5mm Brake Hose Compatibility: Designed with a precise internal diameter tailored to slide smoothly over standard 5mm hydraulic brake lines or oversized mechanical housings.
8.0mm Round Port Architecture: Precision-molded outer ribbing engineered to deliver a snug, secure press-fit inside standard 8.0mm frame ports.
Stress-Reducing Angled Entry: Features a swept, angled orientation that guides cable housings out of the frame at a natural kink-free trajectory.
Premium EPDM Rubber Material: Crafted from a tough, high-density rubber compound that resists cracking, weather rot, and harsh workshop degreasers.
Rattle-Eliminating Fit: Locks your hydraulic housing tightly to the frame chassis, preventing annoying internal cable noise over rough terrain.
Position on Bicycle: Frame tubes (Down tube, top tube, chainstays, headtube junctions)
Installation: Press-fit push insertion
Material: Weather-resistant EPDM rubber
Plug Profile Type: Angled entry / Open cable guide
Frame Port Diameter Compatibility: 8.0mm
Housing/Hose Compatibility: 5.0mm outer diameter (OD)
Removable: Yes
Modern Hydraulic Brake Setups: Perfect if you are running modern hydraulic disc brakes or heavy-duty mechanical systems that utilize 5mm outer lines.
Tight Frame Linkages and Angles: Ideal for dual-suspension mountain bikes or compact road frames where cable housings must exit the frame at an acute angle to clear moving components.
Eliminating Annoying Frame Noise: Excellent for mountain bikers and gravel riders who are tired of hearing their internal lines slam against the inner frame walls on rough trails.
Thin 4mm Shifting Housings: This plug features a 5.0mm inner channel; if used with a thinner 4mm gear cable, it will leave a loose gap that allows water and dust to bypass the seal.
Straight-Line Entry Demands: If your specific frame geometry requires the cable to enter or exit at a perfect 90-degree perpendicular angle to the tube surface, a straight-entry plug is a better fit.
Because these EPDM rubber plugs are designed to fit incredibly tightly inside an 8.0mm frame hole to seal out moisture, sliding them over brand-new, high-friction hydraulic hose can sometimes be a struggle. Apply a tiny drop of liquid rubbing alcohol (isopropyl alcohol) directly onto the brake line before sliding the plug into place. The alcohol acts as an instant, slippery lubricant for easy positioning, and then evaporates completely within minutes, leaving the plug firmly locked onto the housing without any greasy residue!
