Connecting nipple for Starlet trigger gun

The 1/4" M-1/4" M Starlet gun connecting nipple is an accessory fitting used to make a threaded connection between the tube/lance and the Starlet trigger gun. It has a 1/4" male thread on both sides, so it acts as a coupler between two components that have 1/4" female threads. In service, it’s used for repairing joints, replacing worn threads, or reconfiguring an accessory setup.

MPN / reference: 13287
Thread: 1/4" male - 1/4" male

APPLICATION

The nipple is used in typical accessory service work:

• connecting the tube/lance to a Starlet trigger gun on 1/4" threads,
• repairing a damaged or leaking connector in the accessory flow path,
• restoring the correct connection standard after disassembly,
• building a test/service configuration where a 1/4"-1/4" connector is required.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Consider replacing the nipple when you notice:

• leaks at the joint despite correct tightening,
• damaged or worn 1/4" threads,
• cracking, deformation, or mechanical damage after impact,
• difficulty tightening straight (cross-threading tendency),
• recurring leaks after disassembly when threads show wear.

HOW TO CHOOSE THE RIGHT PART

Selection should be unambiguous:

• confirm you need a 1/4" M - 1/4" M connector (two male threads),
• verify the manufacturer number: MPN 13287,
• compare with the removed part: length, shape, any sealing faces, and how it seals in the joint,
• check the condition of the mating threads (tube/gun) - worn female threads can leak even with a new nipple.

With 1/4" connections, axial alignment and thread condition are critical-tightening at an angle quickly damages fittings.

COMPATIBILITY

Select the nipple based on MPN 13287 and compatibility of the 1/4" M - 1/4" M threads with the mating parts (1/4" female threads). Because variants can differ in length and sealing design, safest confirmation is comparison with the removed part.

What is the 1/4" M-1/4" M nipple used for in Starlet accessories?|It connects two components with 1/4" female threads (e.g., tube/lance and the gun), creating a leak-tight joint in the high-pressure flow path.

Is every 1/4" nipple the same if the thread matches?|Not always. Differences can include length, shape, and sealing method. That’s why selection by MPN 13287 and comparison with the removed part is safest.

Why can the joint leak even with a new nipple?|Most often due to worn/damaged female threads in the tube or gun, contamination on the thread, or misalignment during tightening. A nipple won’t compensate for worn threads in the mating component.

How can I avoid damaging 1/4" threads during installation?|Start straight, don’t force the first turns, and clean threads before assembly. If it doesn’t engage smoothly from the first turns, stop and check fitment.

What should I check after installing the nipple on a Starlet gun?|Leak tightness under pressure, no “sweating” at the joint, and that the accessories aren’t loaded at an angle (yanking/twisting the hose can quickly unseal the connection).
