Production environments running 5,000 PSI service lines, high-pressure test benches, hydraulic fluid delivery, water jetting rigs, and oilfield chemical injection need a motorized hose reel where both the pressure-bearing components and the retraction motor are built for sustained daily cycling. The Coxreels HP1125-4-100-AB pairs the #6 Gast cast iron 6-vane compressed air motor (a heavier-duty motor construction than the aluminum 4-vane #4 Gast, with six vanes for smoother torque delivery and a cast iron body that withstands the repetitive load of retracting a full 100-foot drum cycle after cycle in high-frequency production use) with the HP1125 Series high-pressure frame electroless nickel plated steel 90° NPT swivel, AFLAS seals, and 5,000 PSI working pressure rating throughout the fluid path. Direct gear drive (no chain) keeps the mechanism quiet and low-maintenance, while the all-welded 12-gauge steel A-frame, CNC-spun ribbed discs, and permanently lubricated pillow block bearings give the reel the construction depth to match the demanding service environment the HP1125 Series is built for. For installations where the standard 3,000 PSI ceiling doesn't cover the working pressure and the retraction motor needs to handle production cycle counts without premature wear, the HP1125-4-100-AB delivers on both.

Features
- #6 Gast cast iron 6-vane compressed air motor heavier motor construction than the aluminum #4 Gast, with six vanes for smoother torque delivery and a cast iron body suited to high-cycle production retraction use
- Direct gear drive no chain or sprocket; engages the drum directly for quiet, smooth retraction without chain slack, stretch, or lubrication requirements over the reel's service life
- Electroless nickel plated steel 90° full-flow NPT swivel inlet hardened swivel construction rated for 5,000 PSI service; greater pressure capability and corrosion resistance than the brass swivel on standard 1125 Series models
- AFLAS swivel seals fluoroelastomer compound with superior chemical and heat resistance over Nitrile seals, suited to hydraulic fluid, petroleum, chemical, and steam service at elevated working pressures
- Exclusive low-profile outlet riser and open drum slot design provides a non-crimping, flat smooth hose wrap around the drum
- Heavy-duty CNC robotically spun and ribbed discs with rolled edges for greater strength, durability, hose protection, and operator safety
- Sturdy one-piece, all CNC robotically welded 12-gauge steel A-frame base not bolted for superior reel structure; mounting pattern in base for wall, ceiling, floor, or vehicle-body installation
- Permanently lubricated, self-aligning pillow block bearings for trouble-free, smooth drum rotation over extended service life at full production cycle frequency
- Adjustable tension brake prevents free-wheeling during hose deployment; long-lasting chip-resistant, rust-inhibiting CPC powder coat finish; 2-year manufacturer's limited warranty

Applications
- High-cycle hydraulic test & pressure testing facilities production test benches running repeated pressure cycles to 5,000 PSI where automatic reel retraction occurs between every test and motor durability over thousands of cycles matters
- Water jetting & high-pressure surface preparation industrial water jetting rigs and pressure washing operations running above 3,000 PSI where the reel retracts frequently throughout the shift and cast iron motor construction outlasts lighter-duty alternatives
- Oilfield & well service production operations high-frequency chemical injection, stimulation fluid delivery, and well service reel stations where 5,000 PSI working pressure and sustained daily cycle counts demand both the HP1125 pressure rating and the #6 Gast motor durability
- Industrial high-pressure fluid delivery hydraulic fluid supply lines and elevated-pressure process fluid transfer in manufacturing and process facilities where shop air is available for motor retraction and high cycle frequency makes the cast iron motor the preferred choice
- Plant maintenance & MRO at elevated pressure fixed overhead reel stations supplying 5,000 PSI service lines across production floors where the combination of automatic retraction and production-grade motor construction reduces service intervals and downtime
FAQs
Q: What is the difference between the HP1125-4-100-AB (#6 Gast) and the HP1125-4-100-A (#4 Gast)?
A: Both are Gast Manufacturing air motors on the HP1125 Series high-pressure frame, but they differ in motor construction. The #4 Gast uses an aluminum body with four vanes lighter and well suited to moderate retraction frequency. The #6 Gast uses a cast iron body with six vanes heavier construction with smoother torque delivery across a broader duty cycle. The reel frame, pressure rating, swivel, and seals are identical between the two. For installations where the reel retracts frequently throughout the shift, the cast iron #6 Gast is the more durable choice; for lower-frequency applications, the #4 Gast is the standard option.
Q: What is the difference between the HP1125-4-100-AB and the standard 1125-4-100-AB?
A: Both use the #6 Gast cast iron air motor on the same basic A-frame chassis, but the pressure rating and swivel specification differ. The HP1125-4-100-AB is rated to 5,000 PSI with an electroless nickel plated steel swivel and AFLAS seals. The standard 1125-4-100-AB is rated to 3,000 PSI with a machined brass swivel and Nitrile seals. For applications at or below 3,000 PSI, the standard 1125-4-100-AB is the appropriate choice; for applications requiring up to 5,000 PSI, the HP1125-4-100-AB is required.
Q: Does the #6 Gast motor air supply interact with the 5,000 PSI working fluid in the hose?
A: No the #6 Gast retraction motor and the hose working fluid are completely separate paths. The motor connects to a dedicated small-diameter shop air line (90 120 PSI) that powers drum retraction only. The 5,000 PSI working fluid travels exclusively through the hose, outlet riser, and swivel none of which are shared with the motor's air circuit. The two systems operate independently at all times.
Q: What air supply does the #6 Gast motor require for retraction?
A: The #6 Gast motor uses your existing shop air supply (typically 90 120 PSI) through a separate small-diameter air line connection to the motor. Gast does not publish a universal CFM draw figure for this motor in reel retraction service. Confirm your compressed air system can supply both the retraction motor and any connected production equipment simultaneously before installation.
Q: Does the reel come with hose included?
A: No the HP1125-4-100-AB ships less hose. The drum accepts 1/2" ID / 7/8" OD hose up to 100 feet. Select hose with a working pressure rating at or above your system pressure (up to 5,000 PSI) and rated for your specific media. At 5,000 PSI, use hose assemblies with fittings rated and crimped for high-pressure service hose assembly quality at this pressure is a critical safety consideration.
