How to order

Confirm (a) line working pressure and process medium, (b) operating temperature range, (c) bore size and overall length, (d) end fitting type per side (NPT / BSPP / ANSI 150-1500# RF / DIN PN10-PN40 / sanitary tri-clamp / camlock / butt-weld / etc.), (e) braid configuration (unbraided / single / double / triple — drives pressure rating), (f) any required certifications (ISO 10380 PSL class, PED Module, ASME conformance, NACE MR0175, CGA / UL / Chlorine Institute). Indus quotes ex-Dubai for stock items and ex-OEM for build-to-order, with mill test reports and pressure-test certificates included.

Companion products

Pair with matched ANSI flange gaskets, hose clamps, and OEM end-fitting hardware. For high-vibration installations, also specify a Lock-Section or Armor-Flex external hose guard. For fire-rated runs, add a Fry-Sil Fire Jacket or Fire Tape covering. For high-cycle or premium-corrosion service, ask about the matched OEM expansion-joint variant of the same alloy and pressure class.
