The Sealed Pneumatic Internal Gripper for Cast and Rough Bores
The FasTest FIG is a sealed pneumatic internal gripper built for leak testing cast, rough, and as-machined internal bores and tubes. It does two jobs in one tool: gripping collets lock the connector into the bore while an internal seal engages against the wall — so the FIG grips and seals in a single pneumatic motion, without a separate clamp or fixture to hold the part.
As a pneumatic collet gripper, the FIG uses pneumatic actuation to expand its gripping collets evenly against the bore wall. This delivers consistent, repeatable sealing and holding force on every cycle — unlike manual clamping, where force depends on operator effort. Because the collets grip the surface directly, the FIG is optimized for the cast, rough, and irregular bores that smooth-sealing connectors struggle with.
Rated to 120 psi (8.3 bar), the FasTest FIG is designed for operator-applied connections on larger, rough-surface internal bores and tubes — the kind found on castings, housings, and machined components. The gripping collets minimize the need for external fixturing, which simplifies station design and improves operator safety by holding the part securely during the test.
The FIG is available with ICON™ intelligent connection technology, adding SURE SEAL™ digital seal verification, LED feedback, safety interlocks, and real-time data for PLC-integrated automated test stations — turning the sealed pneumatic gripper into a verified, data-driven connection.
The Problem the FasTest FIG Solves
Leak testing a cast or rough internal bore is a problem standard connectors and manual fixturing handle poorly:
-
Rough, cast surfaces won’t seal cleanly: A smooth-sealing connector relies on a clean, machined sealing surface. On as-cast or rough bores, surface imperfections create leak paths, producing false failures and inconsistent results.
-
Holding the part requires fixturing: To resist test pressure, the part normally has to be clamped or fixtured — adding dedicated tooling, station complexity, and a safety risk if the part shifts or releases under pressure.
-
Manual clamping is inconsistent: When sealing and holding force depends on operator effort, force varies from cycle to cycle — and inconsistent force means inconsistent, unreliable test results.
-
Larger, irregular bores need a robust grip: Bigger cast bores and tubes need a connector that can grip a sizeable, imperfect surface securely — something a small smooth seal can’t do.
The FasTest FIG solves all of this as a sealed pneumatic internal gripper: gripping collets hold the part directly (no separate fixture), the design seals on rough and cast surfaces, and pneumatic actuation delivers the same calibrated grip-and-seal force every cycle.
Key Features
Gripping Collets Minimize Fixturing (Pneumatic Collet Gripper)
As a pneumatic collet gripper, the FasTest FIG expands gripping collets against the bore wall to lock itself into the part. The collets hold the connector and the part together against test pressure, so the FIG doesn’t need an elaborate external fixture or clamp to stay in position. On a test station, this eliminates dedicated holding fixtures, simplifies the setup, and improves operator safety by securing the part during the test.
Consistent Pneumatic Sealing Force (Sealed Pneumatic Gripper)
The FIG is a sealed pneumatic gripper: pneumatic actuation engages both the grip and the seal with the same calibrated force on every cycle. Unlike manual clamping, where force varies by operator and fatigue, the pneumatic action delivers consistent grip-and-seal force every time — the foundation of repeatable, reliable leak testing. The pneumatic operation also lets the FIG integrate into automated stations where a PLC triggers connection.
Optimized for Cast and Rough Surfaces (Pneumatic Internal Gripper)
As a pneumatic internal gripper, the FasTest FIG is built specifically for the cast, rough, and as-machined internal bores and tubes that smooth-sealing connectors can’t handle. Its collets grip the imperfect surface securely and its seal accommodates surface roughness, making leak-tight, operator-applied connections on castings, housings, and rough-bore components.
ICON™ Intelligent Connection Technology
The FasTest FIG is available with ICON™ for select models, adding SURE SEAL™ digital seal verification, LED feedback (green = good connection), safety interlock signals, and real-time data output. For automated stations, ICON™ confirms the sealed pneumatic gripper has achieved a verified connection before the test cycle initiates.

Where the FasTest FIG Is Used
Cast Housing & Casting Leak Testing
Castings and cast housings have rough, as-cast internal bores that are difficult to seal with smooth connectors. The FasTest FIG — a sealed pneumatic gripper — grips and seals these rough bores directly, making leak-tight test connections without machining a dedicated sealing surface or building a holding fixture.
Automotive & Powertrain Components
Engine and powertrain components frequently have cast or rough internal bores that require leak testing. The FIG’s pneumatic collet gripper holds and seals these bores with consistent force, supporting high-volume production testing of castings and machined housings.
Fluid Power & Hydraulic Castings
Hydraulic manifolds, valve bodies, and cast fluid-power components often present rough internal bores for testing. The FasTest FIG as a pneumatic internal gripper seals these surfaces and grips the part securely, replacing the smooth connectors and external clamps that struggle on rough bores.
General Rough-Bore Manufacturing
Any application with larger, rough, or as-machined internal bores that need fast, consistent, fixture-free leak test connections benefits from the FasTest FIG — from industrial castings to housings and rough-bore assemblies across a range of materials.

Frequently Asked Questions
Q: What is the FasTest FIG?
A: The FasTest FIG is a sealed pneumatic internal gripper for leak testing cast and rough internal bores and tubes. It uses gripping collets and an internal seal to grip and seal the part in one pneumatic motion, up to 120 psi (8.3 bar).
Q: How does the FIG tool grip and seal?
A: The FIG tool is a pneumatic collet gripper — pneumatic actuation expands the collets against the bore wall with consistent force, gripping the part and engaging the internal seal at the same time. No separate fixturing is required to hold the part.
Q: What is a sealed pneumatic gripper?
A: A sealed pneumatic gripper is a connector that both grips and seals a part using pneumatic actuation. The FasTest FIG grips the bore with collets and seals against the wall in a single motion, making it ideal for rough or cast surfaces that need both holding force and a leak-tight seal.
Q: What surfaces is the FasTest FIG designed for?
A: Cast, rough, and as-machined internal bores and tubes — surfaces where a smooth-sealing connector would leak. The FIG is optimized for larger, rough-surface internal bores on castings, housings, and machined components.
Q: What is the pressure rating of the FasTest FIG?
A: The FasTest FIG is rated for vacuum to 120 psi (8.3 bar), covering the leak and pressure-decay test requirements for the cast and rough-bore components it is designed for.
Q: Why does the pneumatic collet gripper minimize fixturing?
A: Because the gripping collets lock the connector and the part together against test pressure, the FIG holds the part itself — so a separate clamp or holding fixture isn’t needed. This simplifies the station and improves operator safety.
Q: Is the FasTest FIG a pneumatic internal gripper?
A: Yes — the FIG is a pneumatic internal gripper that grips and seals inside a bore using pneumatic actuation. It is built specifically for internal cast and rough-surface bores and tubes.
Q: Why is pneumatic actuation important?
A: Pneumatic actuation delivers the same calibrated grip-and-seal force on every cycle, unlike manual clamping where force varies by operator. Consistent force is essential for repeatable, reliable leak testing.
Q: Can the sealed pneumatic gripper be automated?
A: Yes — the FIG offers pneumatic, semi-automated, and fully-automated actuation, and ICON™ adds seal verification and real-time data for automated test stations.
Q: What industries use the FasTest FIG?
A: Automotive and powertrain castings, fluid power and hydraulic castings, industrial housings, and general rough-bore manufacturing — anywhere larger, cast, or rough internal bores need fast, consistent, fixture-free leak test connections.
