We can actually do a lot with these in terms of customization — different flange sizes, thread standards like DIN or ANSI, even the galvanized finish thickness if you're running a high-pressure system that's hard on parts.
Most buyers go with the brass body for corrosion resisance, and it's pretty much a standard fit for refrigeration lines or industrial sight glasses where you need to see flow or level clearly.
The round head design makes instalation straightforward, but keep in mind it's not ideal for every low-pressure setup — the flange connection is built for high-pressure environments, so a simple glass tube might be easier for gentle stuff.
Anyway, we usually have stock on the common standards like GB or BSW, give or take 100 units or so, but for custom logo imprinting or bulk synthesis of small vials, lead time can bump to 4 weeks (check the COA before ordering).
it come in boxes as standerd packaging, roughly 20 pieces per box, and we can share the TDS and HPLC results upon request — one detail we've noticed is that the galvanized surfce holds up better in humid conditions than plain brass, which most spec sheets won't mention.
Our MOQ is typically 50 units for standard sizes, but we can discuss smaller orders depending on stock availability.
Yes, we can provide material certificates and a test report for the galvanized surface upon request. Just let us know what you need.
We can adjust the flange to DIN, ANSI, GB, JIS, or BSW standards as needed. For custom sizes outside these, please get in touch with your specs.
Standard lead time is about 20-25 days for 200 units, but we can expedite if you need them faster—just check with us first.
Each unit is packed in a box with foam padding to prevent damage. For bulk orders, we use sturdy cartons or wooden crates depending on quantity.
