5.5 MATERIALS
5.5.1 Material for Most Fittings
Unless otherwise noted, the RP2000-Series fittings shall be made of mild steel, AISI type
B113, or any AISI-type low-carbon, hot, or cold-rolled steels, in accordance with FED-STD-66, having
chemical compositions within the following ranges:
Carbon
Manganese
Phosphorus
Sulphur
Lead
(C)
(Mn)
(P)
(S)
(Pb)
0.08% to 0.25% max
0.25% to 1.15% max
0.04% to 0.12% max
0.05% to 0.35% max
0.15% to 0.35% max
5.5.2 Optional Material for RP2330
The RP2330 adapter may be fabricated from polyamide (nylon) in accordance with L-P-410 or
ANSI/ASTM-D4066 whenever installations require that the RP2330 insulate the connector from
conduit.
5.5.3 Optional Material for RP2350
The RP2350 adapter may be fabricated from aluminum alloy in accordance with QQ-A-225 or
ASTM-STD-B85 provided that minimum spacing requirements for aluminum backshells as delineated
in paragraph 7.7 are met.
5.5.4 Material for RP2440
The RP2440 adapter shall be fabricated from polyamide (nylon) rods or tubes in accordance
with L-P-410 or molded from nylon molding plastic in accordance with ANSI/ASTM-D4066. An
optional material is the "super tough" nylon identified by the Dupont trade name "Zytel" ST801 (or
equivalent). Super tough nylon comes in stock shapes for machining, or it can be molded.
5.6 FINISH
5.6.1 Finish for Steel Fittings
The finish on the steel fittings shall be electroless nickel in accordance with SAE AMS 2404C
Electroless Nickel Plating.
5.6.2 Finish for Aluminum Fitting
The finish on the aluminum fitting shall be electroless nickel in accordance with SAE AMS
2404C Electroless Nickel Plating.
5.7 WORKMANSHIP
Fittings shall be fabricated so that they are uniform in quality and free from defects that could
make the fitting unsatisfactory for the intended purpose.
