Specifications

An extremely lightweight suction hose, the DRAFTEX® single jacket construction uses 100% spun polyester combined with a helical interior reinforcement. It is lined with TPU elastomer and encapsulated with red DRAFTKOTE™ to enhance durability. With a service test pressure rating of 300 PSIG (2100 kPa) DRAFTEX® is designed for Forest Service use with portable pumps as well as other pump applications. Patent No. 2168497.

Length: Up to 20' (6,1 m).

DRAFTEX® specifications

The hose shall be a single jacket construction of 100% virgin spun polyester, DRAFKOTE™ treated, combined with a special helical interior reinforcement.
There shall be a minimum of 14.0 filler yarns per inch in the jacket.
The thickness of the lining shall be 0.030" (762 µm) minimum and it shall be constructed of extruded T.P.U. elastomer.
The outside jacket shall be treated with DRAFTKOTE™ elastomer which shall completely encapsulate the jacket fibers and not merely surface coat the jacket.
The hose service temperature range shall be -60°F to 140°F (51°C to 60°C).
FM abrasion test of 3,000 cycles minimum.
At 600 PSIG (4200 kPa), its elongation shall not exceed 6% of the initial hose length, it shall not warp more than 10 inches (25 cm) and should not rise from the test table.
The hose shall not twist more than 10 turns per 100 ft (30,5 m) while at 450 PSIG (3150 kPa).
Minimum service test pressure of 300 PSIG (2100 kPa).
Minimum proof test pressure of 600 PSIG (4200 kPa).
Minimum straight burst test pressure of 900 PSIG (6300 kPa).
The hose while curved to a radius of 27" (69 cm) shall not burst at less than 900 PSIG (6300 kPa).
Minimum vacuum test pressure of 25 inches of mercury (84,7 kPa).
