Air tube PAR-CAM-015

for compressed airpneumaticpolyurethane

Overview
Pneumatic expanding shaft accessories and spare parts for air shafts from EJEMATIC are designed for companies that cannot afford production downtime. When a production line stops because of poor reel gripping, worn components or slow reel changes, you lose productivity and money. We supply air chambers, chamber protectors, connectors, clamping jaws, expanding strips, valves, reel stops and inflation tools built to simplify maintenance, speed reel changes and reduce downtime. Standard stocked items ship within 24–48 h.

Main product families & description

• Air chamber assembly — chamber, protector and air connection that store compressed air for expansion. Chambers in polyurethane; available by the meter (rolls) with polyester protector or supplied as custom-sized units/strips (kits include chamber, protector and connection).
• Clamping jaws — kits of sealing parts that ensure airtight chamber ends; available one-hole, two-hole and lower clamping jaw configurations. Aluminium versions and kits with pins included.
• Expanding strips (listones) — contact element transferring chamber expansion to the reel inner surface; offered in linear or segmented geometries and various materials to suit core type and grip requirements.
• Valves and fittings — brass connectors, non-return valves and rotary fittings for controlled inflation and deflation; available in thread types such as 1/8G and M8 and compatible with 6 mm tubing.
• Accessories — reel positioning stops, pneumatic inflation guns and spiral pneumatic hoses (Ø6) to simplify inflation and improve operator ergonomics.

Materials & options

• Chamber material: polyurethane — specified for repeated inflation/deflation cycles and long service life.
• Protector: polyester film — protects chamber from abrasion; supplied with chambers ordered by the meter or in kit format (example: PAR-POL-015).
• Expanding strips: rubber (high friction), aluminium (durable, lower friction) and knurled aluminium (enhanced grip for cardboard cores); profiles include linear, segmented and serrated finishes.
• Clamping jaws and seals: aluminium options available; kits sold with required pins and components.
• Valves and fittings: brass non-return valves and connectors; thread options include 1/8G and M8; rotary inflation fittings for continuous supply (suitable for 6 mm tube).

Delivery & service
Standard deliveries: 24–48 hours for stocked spare parts and accessories. Components are grouped by family to simplify ordering and reduce downtime. Custom-sized strips and special kits available on request.
