Fishman Luer Lock Syringe Barrels are designed for industrial use. Every syringe barrel is silicone-free and has a zero taper barrel I.D. The thick wall design averts  bursting and cracking.

Syringe assemblies for use with air pressure consist of a syringe barrel and an adaptor with O-ring. Needle Tiplets are sold separately. Adaptors are made from injected-molded polypropylene and include an O-ring. Made in USA.
