D38999/20FA98PN is a Series III circular connector under MIL‑DTL‑38999 specification. Quite a few overseas engineers mix up PN and PA suffix. They share identical insert layout, yet differ in mating polarity. The suffix matters a lot during part selection.

The code 98 inside part number stands for its insert arrangement, which defines contact count, size and inner spacing. Mating will fail if insert arrangement does not match between plug and receptacle. This model comes with built‑in scoop‑proof shell structure. Shell sections align before pins make contact, preventing pin and insulator damage caused by angled insertion.

Manufactured according to ARINC, SAE and RTCA standards, it delivers good cross‑part interchangeability. We cover full production steps including mould tooling, CNC shell machining and assembly. Every unit gets individual quality inspection after assembly.

We support both sample orders and large‑volume project demands. It works well for airborne‑grade industrial equipment and test systems, offering reliable alternative solutions for global purchasers.

Mass production

D38999/20FA98PN is Series III circular connector under MIL‑DTL‑38999 specification. Every unit follows standardized steps, starting from mould development all the way to overseas shipment.

We start with mould tooling. Moulds produce insulators and sealing‑body parts. CNC precision machining handles metal hardware, making plug shell and socket shell separately. Insulators and sealing parts are assembled into insulator components, then combined with machined shells to build finished D38999/20FA98PN connectors.

Assembly is not the final step. Every batch of D38999/20FA98PN goes through dedicated inspection. We test shell dimension, No.98 insert arrangement and scoop‑proof performance against MIL‑DTL‑38999 specs, filtering out defective units.

Qualified goods move to packing area for protective packaging and warehouse storage. According to overseas order requirements, we arrange express, air or sea shipment for delivery.

Specification

D38999 dust caps protect mating faces of plugs and receptacles. They keep dust, moisture and hard debris away from contact inserts. Fitted with tether chain, they stay attached and will not get lost after disconnection.

Clear part‑numbering rules are applied. Code 32 stands for plug dust cap, while 33 is for receptacle dust cap. Multiple plating options are available, including olive drab cadmium and electrolyses nickel. Shell sizes cover 09 to 25. Two stainless‑steel tether types are offered: rope with ring or rope with hole for different mounting needs.

Dimension drawings cover two main groups. One fits D38999/26 plug connectors, the other works for D38999/20 and D38999/24 receptacles. You may refer to drawings for cable hole diameter, main body size and tether length during part selection.

These dust caps are manufactured to match MIL‑DTL‑38999 supporting standards. Plating and shell dimension maintain full interchangeability with original accessories. We supply all shell sizes for sample testing and bulk orders. They help extend connector service life for airborne and field‑use industrial equipment.

D38999/20FA98PN is a precision MIL‑DTL‑38999 series connector. Its gold‑plated pins are sensitive to bump damage and static electricity, so we take targeted protective measures while packing.

After full‑range quality checks, each connector gets individual anti‑static protection. This keeps pins from scratches and safeguards the scoop‑proof shell structure during transit. Units are grouped into anti‑static inner boxes, then packed into heavy‑duty export cartons with cushion fillers to absorb vibration from air or sea transport. Outer cartons are clearly marked with part number D38999/20FA98PN, batch info and quantity for easy receiving check.

We offer multiple shipping options. Small sample orders can go via DHL, FedEx, UPS, TNT or EMS express. For bulk project orders, air freight and sea freight are available, covering most countries worldwide.

We track logistics status from finished inspection, packing, customs clearance down to final delivery. Whether you need small sample lots or large‑volume project orders, proper packaging and shipping solutions are arranged to help D38999/20FA98PN arrive in good condition.
