Graco 100030 Bushing — Compatibility & Specs
Compatible Machines
This Graco 100030 Bushing (thread reducer 1/4 M x 1/8 F, NPT) is used where a 1/4" male port must accept a 1/8" female connection. It appears in OEM parts lists for the following equipment families:
- GX-7 Spray Gun family
- E-8p proportioner / machine assemblies
- Other Graco spray rigs or guns that require a 1/4 M to 1/8 F NPT adapter (verify in your model’s parts manual)
What is the Graco 100030 Bushing?
A compact, precision-machined bushing used as a thread reducer/adapter in air or fluid paths on Graco equipment. It converts a 1/4 male NPT port to a 1/8 female NPT connection, helping integrate gauges, valves, hoses, or line components that use smaller 1/8" threads.
Quick Specs
| OEM Part | Graco 100030 — Bushing |
|---|---|
| Thread Type | NPT (National Pipe Thread) |
| Thread Size | 1/4" Male NPT → 1/8" Female NPT |

| Position | Varies by model (air line or fluid line interfaces; see your parts diagram) |
Fitment Tips & Verification
- Match both threads: 1/4" NPT (male) side into the body/manifold & 1/8" NPT (female) side for the attached component.
- Consult your model’s parts manual: look for 100030 in the exploded views to confirm exact location and quantity.
- Use compatible thread sealant (PTFE tape or pipe dope rated for your material and pressure) as specified by Graco guidelines.
- Do not over-torque: NPT seals by thread interference; overtightening may crack mating parts or distort the bushing.
Frequently Asked Questions
Check your unit’s parts list or exploded diagram. If it specifies Graco 100030 Bushing or calls for a 1/4 M x 1/8 F NPT reducer at that position, this is the correct part.
Commonly at manifold ports, regulators, gauge take-offs, or gun/rig interfaces where a 1/8" component needs to be adapted to a 1/4" port. Location varies by model (air or fluid side).
Yes—NPT is a tapered thread. Use PTFE tape or a suitable pipe sealant compatible with your coating/foam chemistry and pressure. Avoid contaminating downstream passages.
It appears in parts lists for GX-7 gun assemblies and E-8p machine assemblies. Always confirm against your specific revision/serial parts manual before ordering.
Use the exact size and part number specified. Reducers come in multiple thread sizes; ordering by Graco OEM number (e.g., 100030) avoids mismatch.
