Fittings Specs-Codes
*Fittings* > Codings are a nightmare particularly threads, tubing sizes, types of connector-endpieces/ CHROMTECH specialises in Laboratory type Applications Tube Sizes from capillaty to ~3/8” NOT larger industrial types & sizes - these are available to Order but often Import and MOQs are required and currently with CP / COVID extensive lead times ( almost prhibitive) *GOOD As VP are we are seeking other sources of similar Plastic Fittings that are More “reliable”* *NOT Just as another reseller ! but direct from”Fair Dinkum”OEMs*	. . . > this is an attempt by *Chromtech* to rationalise a Coding System appllicable for Customers / End-Users specifying “exactly” what they want for a particular APP simplifying Ordering parts from Us ! we source and “translate” for you “Cat.#s, Part.#s etc for various OEMs & pretenders who we have sorted out FOR YOY ! There are in fact countless OEMs worldwide offering often similar “parts” perhaps with the same or very similar specs but How many of theses Chinese would YOU TRUST ? Some are more “exotic”, some for more specific APPS But MANY are just resellers of resellers or unidentified “OEMs” ALL fittings OEMS have ”bastardised” Codes to suit and have their own individual “generalised” system

Barb Styles-A

Barb Styles-B
in hindsight during COVID19 VP are struggling to produce due to Govt demands
possibly just copies of other OEMs commercial products just aimed by them to “lock-in customer as replacement items” for their own products
“mass production” in case it ever eventuates
might explain why some VP items have MOQs or
10,000 or higher

in hindsight probably VP has proven to have been a bit too ambitious / over-commited since a
“start-up” in the ‘90s

ALL of these barb seem to be offered even tho’ arguably of Only “academic” interest perhaps ?

Ceetainly for low production R&ED purpose most od these are interchangable for all intentents & purposes

MOST lab / Industrial OEMs standardise on a Series200 barb-type for medium>Most Applications
