Claim 0:
1. A fluid system comprising:
a first conduit section including:
a first beveled surface at a first end of the first conduit section;
a cylindrical surface;
a first conduit bore extending from the first end of the first conduit section to a second end of the first conduit section,
the first conduit bore including:
a first interior beveled surface proximate the first end of the first conduit section, and
a first inner surface spaced from the first end of the first conduit section by the first interior beveled surface, and

the first interior beveled surface and the first inner surface at least partially defining a first fluid passageway,

a first surface circumscribing the first conduit bore,
the cylindrical surface being between the first surface and the first beveled surface,
the cylindrical surface and the first surface forming a seal seat, and
the first interior beveled surface extending from the first surface to the first inner surface; and

a first edge located between the first surface and the first interior beveled surface;

a second conduit section including:
a second beveled surface at a first end of the second conduit section;
a second conduit bore extending from the first end of the second conduit section to a second end of the second conduit section,
the second conduit bore including:
a second interior beveled surface proximate the first end of the second conduit section, and
a second inner surface spaced from the first end of the second conduit section by the second interior beveled surface,

the second interior beveled surface and the second inner surface at least partially defining a second fluid passageway, and
the first end of the first conduit section being coupled to the first end of the second conduit section to fluidly connect the first fluid passageway and the second fluid passageway,

a second surface circumscribing the second conduit bore,
the second interior beveled surface extending from the second surface to the second inner surface,
the first beveled surface being configured to abut the second beveled surface,
the second beveled surface extending between the second surface and an exterior surface of the second conduit section,
the second surface being between the second beveled surface and the second interior beveled surface,
the second beveled surface and the second interior beveled surface being on opposite sides of the second surface,
the first beveled surface and the second interior beveled surface being on opposite sides of the second surface, and
the seal seat being between the first beveled surface and the first interior beveled surface, and

a second edge located between the second surface and the second interior beveled surface;

a seal disposed between the first surface and the second surface,
the seal resting on or being inserted into the seal seat, and
an entirety of the seal being recessed from the first edge and the second edge; and

a coating applied to the first interior beveled surface and to the second interior beveled surface.
