I've run for years on several tubes that had no bead what so ever (for the same reason), and the hoses never blew off.<!-- google_ad_section_end -->
Or - you could just drill 4 to 8 #30 (1/8") holes around the circumference of the tube about 1/4" from the end and install pop rivets.. Works well - no leaks since the hose is clamped beyond the rivets.
Randy: any problem with using aluminum rivets on a stainless pipe? Issues with dissimilar metals? I was contemplating adding the rivets as you describe, but was concerned about the dissimilar metals, corrosion, and a bit of metal coming off and flowing through the system
On a separte note, I have used double clamps in all critical locations for a bit of added security, a techique used on marine through hulls where a failure could literally sink the boat.
