Borehole, seal
and connection method.
Match the packer family to the substrate and delivery method. Borehole diameter, body length, seal and nipple describe separate characteristics.
Different designs, different anchoring conditions.
Control of anchoring, sealing and process observation.
HAMMPACK expansion packers combine a steel body with a seal matched to the nominal borehole. Selection in this group goes beyond diameter: anchoring zone, borehole condition and observing material transfer also matter.
Model body and selected connection — shown separately.Conical connection. Select a compatible conical coupler. Approximate passage for the M6×1 version: Ø1 mm.
PI-SPH 10/110
Ø10 mm borehole · 110 mm length · 39 mm sealSteel packer for a Ø10 mm borehole. Open the product page and compare the available nipple versions.

PI-SPHW 10/110
Ø10 mm borehole · 110 mm length · 39 mm sealAnchoring wings and a progressive increase in diameter help secure the packer in soft or irregular substrates. Test anchoring in the actual material.
Model body and selected connection — shown separately.Conical non-return nipple. Connect a compatible conical coupler; check the installation and thread-sealing method for the supplied version.
PI-SPH 14/110
Ø14 mm borehole · 110 mm length · 38 mm sealModel for a larger nominal borehole. A larger borehole affects anchoring and material consumption, but does not determine flow through the nipple.
Steel packers for different anchoring depths.
Diameter, length and seal position determine the fit to the borehole. On larger versions, a flat-head nipple connects to the appropriate coupler.
Flat-head nipple screwed onto the body. For connection to a flat-head coupler.
PI-SPM 16/300 FWG
Ø16 mm borehole · 300 mm lengthSingle 37 mm seal. Steel packer with a flat-head nipple.
Model body and selected connection — shown separately.Conical non-return nipple for connection to a conical coupler.
PI-SPM 10/110
Steel · Ø10 mm borehole · 110 mm lengthExpansion packer with a single 39 mm seal. Match the nipple version to the coupler and how you intend to observe material transfer.
Flat-head nipple screwed onto the body. For connection to a flat-head coupler.
PI-SPM 18/300 FWG
Extended body · flat-head connectionChoose the body length, sealing zone and nipple to suit the coupler.
Drive-in and surface-bonded packers: two different delivery methods.
Drive-in packers are installed in a prepared borehole. Surface-bonded packers create an injection point on the structure's surface. The choice depends on crack access, substrate condition and required delivery conditions, not just body material.
Model body and selected connection — shown separately.Plastic drive-in packer for a prepared borehole. Install using the appropriate driving tool; the connection method is specific to this version.
PI-P 12/65
Drive-in packer · plastic · Ø12 mm boreholeAn injection point in a prepared borehole. Match the driving tool and coupler to the nipple and check the operating limit in the current product data.
Model body and selected connection — shown separately.Drive-in packer in blue plastic with a flat plastic nipple. For epoxy resins, polyurethane resins and silicate solutions.
PI-PH 12–14/65F
Drive-in packer · Ø12–14 mm · length 65 mmFor crack injection in brick, sand-lime brick, hollow blocks and sandstone. Connects to a flat-head coupler. Up to 80 bar in accurately drilled holes in solid material.
Model body and selected connection — shown separately.Transparent packer bonded to a prepared surface. It creates an injection point on the crack surface; attachment also depends on the adhesive and substrate.
Transparent PI-PG M6
Surface installation · M6 nipplePacker bonded to a prepared surface. The transparent body aids observation; bond strength also depends on the adhesive and substrate.
Passage size, material particles and connection control.
Mineral suspension requires a delivery path suited to its viscosity and particle size. A narrow valve passage can restrict the system despite a large packer body. Select the packer, coupler, valve, hose and pump as a complete system.
Body without a delivery fitting. Choose the appropriate valve or nipple to match this model's thread.
PI-JG 18/150
Accessory for the JG lance systemSeals the inlet end of the lance system. Match it to the connections and injection point position in the complete assembly.
Body without a delivery fitting. Choose the appropriate valve or nipple to match this model's thread.
PI-CEM 14/100
Plastic · Ø14 mm borehole · Ø7,5 mm passageSuspension packer with a 1/4 inch thread, for use with a suitable coupler or flat-head nipple.
Model body and selected connection — shown separately.Injection pliers for operating a compatible connection. They are a delivery-path accessory, not a packer installed in a borehole.
PI-PLIERS
Mating accessory · injection pliersFor connecting a compatible injection fitting. They are part of the delivery path, not a packer installed in a borehole.
Choosing the nipple and non-return seal deliberately.
In PI-SPM ECO steel packers, the body and rubber seal match the professional version. The key difference is the budget nipple, mechanically tightened to the packer. This is what reduces the packer cost.
Model body and selected connection — shown separately.The ECO nipple reduces packer cost. With low-viscosity materials, it may leak under back pressure.
PI-SPM 10/110 ECO
Steel · Ø10 mm borehole · ECO nipple110 mm body, 39 mm seal and economical ECO nipple.
Model body and selected connection — shown separately.The ECO nipple reduces packer cost. With low-viscosity materials, it may leak under back pressure.
PI-A 13/100 ECO
Aluminium / steel · 100 mm body · ECOFor a Ø14 mm borehole, with a split seal.

PI-SPM 13/110 ECO
Steel · Ø14 mm borehole · 110 mm bodySingle 39 mm seal and ECO nipple. A larger borehole changes anchoring and material consumption; it does not remove valve limitations.
Imperial packers. For imperial drill bits.
Packers for the American market, where imperial drill bits are used. A 3/8″ bit is 9,525 mm in diameter and a 1/2″ bit is 12,70 mm. The packer seal is matched to these dimensions.
PI-SPH 3/8″
3/8″ borehole · 9,43 mm sealSteel expansion packer with a conical nipple, for boreholes drilled with a 3/8″ bit.
PI-SPH 1/2″
1/2″ borehole · 12,70 mm sealSteel expansion packer with a conical nipple, for boreholes drilled with a 1/2″ bit.
PI-SPHX 3/8″
3/8″ borehole · one-day versionThe lower valve remains in the expansion zone after the upper packer section is detached.
Drill bit wear changes the borehole.
Check drill bit wear and the actual borehole diameter. Choose the packer seal so it can expand against the substrate.
| Model | Seal |
|---|---|
| PI-SPH 3/8″ | 9,43 mm |
| PI-SPH 10 | 9,84 mm |
| PI-SPHW 10 | 9,84–11,4 mm |
| PI-SPH 1/2″ | 12,70 mm |
PI-SPHW progressive wings help the seal adapt to borehole irregularities.
One-day packers.
Two valves allow the upper packer section to be detached after injection. The lower valve and seal remain in the borehole, so the point can be closed without waiting for the injected material to cure fully.
Model body and selected connection — shown separately.Conical nipple for connection to a conical coupler.
PI-SPX 10/110
One-day packer · steel · Ø10 mm boreholeValve in the expansion section, 110 mm body and 49 mm seal. Match the anchoring depth to the element thickness.
The expansion zone stays in place
The lower valve retains the injected material, while the retaining ring holds the rubber expanded. After the upper section is unscrewed, the seal remains pressed against the borehole walls.
Inject resin. Unscrew the upper section.
The packer is inserted before expansion. The rubber is longer and smaller in diameter.

Aluminium? Check the stem too.
The term “aluminium packer” can mean an aluminium body with a zinc-plated steel stem. An aluminium body alone therefore does not rule out steel that can corrode. HAMMPACK goes further: in our 100% aluminium version, both the body and stem are made from aluminium.
Aluminium body, steel stem
Typical aluminium packer constructionAluminium refers to the body. The steel stem remains steel, even when protected by a zinc coating.
