Series: FIRG Q
Interchange: ISO 16028
Q variation of the FIRG series is the integration of the QPQ plating
technology combined with a coupler constructed of stainless internal
parts and carbon steel external parts of the flat face quick couplings.
In relatively corrosive, alkaline environments they are an excellent
alternative to the more expensive stainless steel quick couplings and
demonstrate a much higher operational pressure performance. The
interchangeability of FIRG Q series couplings is in accordance with
ISO 16028.
- Material: high resistance carbon steel treated with QPQ
- Valve parts in stainless steel
- Springs in AISI 302 SS
- Locking balls in AISI 420
- Seals: Nitrile, EPDM, Viton, etc.

Flat Face with QPQ Plating
Flat Face: QPQ Plating
Overview
The FIRG Q flat face couplings
series is the solution for mildly
corrosive environments and/or
for relatively corrosive fluid
transfer (i.e. sweet water, water
and glycol etc). The internal
valve material is stainless steel
AISI303 and can be supplied
with a variety of seals for fluid
compatibility and operating
temperature requirements.
The combined features of FIRG
Q series are ideal for several
applications, mainly in the
industrial field.
Applications
FIRG Q series are suitable
for low or medium corrosive
fluids. steel mills, tire
manufacturing, state or
municipal right-of-way spraying.
