Product Information
Full details
The Laser Silicone Hose without Valve (6819) is a essential tool for automotive technicians and DIY mechanics who require a reliable fluid transfer line for brake bleeding systems. This 1.2-meter high-quality hose is engineered to provide a secure and flexible connection for a variety of Laser brake bleeders, including the popular model 6783. While it offers excellent durability and chemical resistance for automotive fluids, users should be aware that this specific version does not include an integrated one-way valve, which may require manual flow control depending on your specific bleeding procedure.

FAQs
Does this hose come with a one-way valve?
No, this is the valve-less version (6819). If you require a one-way valve, please look for Laser Part No. 6820.
Is this hose compatible with non-Laser brand bleeders?
While designed for Laser systems, the universal fit allows it to work with many standard bleed nipples; however, fitment may vary depending on the specific diameter of your tool's inlet.
Can I use this for power steering fluid?
This hose is specifically designed for brake bleeding applications and is compatible with standard brake fluids. Avoid using it for high-pressure hydraulic applications.
How do I store the hose to keep it flexible?
Store in a cool, dry place away from sharp objects and direct UV light to prevent the silicone from aging.
What should I do if the hose gets a kink?
Silicone usually recovers its shape easily. If it remains kinked, warm the hose slightly in warm water to help it return to its original form.
Troubleshooting
Hose slipping off the bleed nipple
Ensure the bleed nipple is clean and dry; if the fit is loose, use a small hose clamp or cable tie to secure the connection.
Fluid leaking at the connection point
Trim a small portion (1-2cm) off the end of the hose to create a fresh, tight seal against the nipple.
Hose is becoming stiff
While silicone is durable, exposure to extreme heat or certain cleaners can affect it; replace the hose if cracking or significant stiffness occurs.
Pros and Cons
Pros
- Compatible with a wide range of Laser brake bleeding equipment
- Flexible material makes reaching tight spaces easier
- Generous 1.2-meter length allows for comfortable working distances
- Durable silicone construction resists common shop chemicals
Cons
- Lacks an integrated one-way valve for preventing fluid backflow
- Requires manual monitoring to prevent air re-entry into the system
- Not intended for high-pressure hydraulic lines
Setup, Compatibility & Care
To set up the hose, simply press the end firmly onto the vehicle's brake bleed nipple. If the nipple is slightly undersized, ensure the hose is fully seated to prevent fluid leakage. The hose is designed for a universal fit across Laser-branded maintenance tools. To maintain the life of the silicone, wipe the exterior with a clean shop rag after use to remove stray brake fluid, as long-term exposure to certain aggressive chemicals can eventually cause surface hardening. Store the hose away from direct sunlight or sharp metal objects that could puncture the silicone wall. If the hose becomes contaminated with dirt, rinse with warm water and allow it to air dry completely before the next use.
