This part is an after market accessory for motorcycles. It will be a reorder part and will need packaging as well as manufacture.
The piece begins with a plastic hand syringe, moves to a two way aluminum valve with an attached 15 psi gauge. Flexible tubing then moves to the alluminum attachment with an o-ring inserted inside and a threaded inside.
I have many detailed pictures and will send the actual part when we have reached an agreement. I will need a quotation with several quantities, port of lading and shipping details to include carton size, weight and item count.
