I always assumed Halkey-Roberts was one company.
The Bullet tube I'm using for the last few years came with what were described as "Halkey-Roberts" Valves.
From their website:

The smaller backrest urethane tube bladder has the blue valve (above centre) which is supposed to be for oral filling.![[Image: view2.jpg]](http://www.halkey-roberts.com/images/view2.jpg)
And the main urethane bladder comes with one of those black on the outside orange on the inside valves. (above left and centre)
I have not had any problems with either kind of valve from a reliability point of view, but if you are using an air pump, the blue type has those milled edges (like a coin) and if you are pushing on an adapter airtube air can leak through the tiny slots, extending the inflation time a bit. Not enough to be a problem, but if you had a choice the black-orange type fits our particular needs better.
