High-pressure applications that need the maximum 325-foot reach of the HP1125 Series with automatic air-motor retraction hydraulic test facilities, oilfield service stations, water jetting operations, and elevated-pressure fluid delivery points where shop air is available at the reel mount get push-button retraction across the full 5,000 PSI capable drum from the Coxreels HP1125-4-325-A. The #4 Gast compressed air motor (a Gast Manufacturing aluminum 4-vane air motor that powers automatic drum retraction from your existing shop air supply through a separate small-diameter air line entirely independent of the 5,000 PSI working fluid path through the drum hose) pairs with direct gear drive (no chain gears engage the drum directly for quiet, smooth retraction without chain stretch or lubrication intervals) on the HP1125 Series high-pressure frame. The electroless nickel plated steel 90 NPT swivel hardened for 5,000 PSI service over the brass swivel on standard 1125 models and AFLAS seals give the fluid path the material specification that sustained high-pressure service demands across the full 325-foot hose length. For fixed installations where shop air is already present at the mount point, the 5,000 PSI working pressure exceeds what the standard 1125 can handle, and 325 feet of reach is required from a single reel station, the HP1125-4-325-A delivers all three without requiring electrical infrastructure at the reel.*Note: The above product image is for illustration purposes only.

The #4 Gast motor connects to a dedicated small-diameter shop air line (typically 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. At 325 feet, the two circuits remain fully independent across the entire drum and hose length.Q: When should I choose the #4 Gast (-A) over the #6 Gast (-AB) on the 325-foot drum?A: The #4 Gast aluminum motor is appropriate for the 325-foot drum when the retraction cycle frequency is moderate the reel retracts a manageable number of times per shift at this capacity, and the aluminum motor body handles the drum load without sustained thermal stress. The #6 Gast cast iron motor is the better choice for high-cycle production environments where the reel retracts frequently throughout the shift, since the cast iron body manages heat better under the sustained startup load of the maximum-capacity drum. At 325 feet the heaviest drum in the HP1125 Series if there is any uncertainty about the duty cycle, the cast iron #6 Gast provides a meaningful durability margin over the aluminum #4 Gast.Q: What is the difference between the HP1125-4-325-A and the standard 1125-4-325-A?A: Both use the #4 Gast aluminum 4-vane air motor on the same basic chassis with direct gear drive. The difference is working pressure and swivel specification. The HP1125-4-325-A is rated to 5,000 PSI with an electroless nickel plated steel swivel and AFLAS seals. The standard 1125-4-325-A is rated to 3,000 PSI with a machined brass swivel and Nitrile seals. For applications at or below 3,000 PSI, the standard 1125-4-325-A is the more economical choice; for applications requiring up to 5,000 PSI, the HP1125-4-325-A is required.Q: What air supply does the #4 Gast motor need to retract a fully loaded 325-foot drum?A: The motor uses existing shop air (typically 90 120 PSI) through a separate small-diameter air line. Gast does not publish a universal CFM figure for this motor in reel retraction service. On the 325-foot drum the heaviest load in the HP1125 Series the motor faces greater startup inertia than on shorter drums; confirm your compressed air system can deliver stable pressure under the maximum drum load while simultaneously supplying connected production equipment.Q: Does the reel come with hose included?A: No the HP1125-4-325-A ships less hose. The drum accepts 1/2″ ID / 7/8″ OD hose up to 325 feet. Coxreels recommends SAE 100R16 wire braid hose for HP1125 Series reels a two-wire braid construction rated for hydraulic and high-pressure oil service at up to 5,000 PSI and 250F. Use assemblies with fittings rated and crimped for high-pressure service, and verify hose OD does not exceed 7/8 inch to ensure correct drum wrap.body{margin:0;padding:0;overflow-x:hidden;}.spec-accordion{width:100%;max-width:1100px;margin:1em auto;font-family:Verdana,Arial,sans-serif;}.spec-accordion-toggle{width:100%;display:grid;grid-template-columns:32px 1fr 32px;align-items:center;gap:8px;text-align:center;cursor:pointer;background:#444;color:#fff;border:0;padding:12px 16px;font-size:16px;font-weight:700;text-transform:uppercase;}.spec-accordion-title{grid-column:2;text-align:center;text-transform:uppercase;}.spec-accordion-icon{grid-column:3;text-align:right;font-size:20px;font-weight:700;}.spec-accordion-panel{border:1px solid #cfcfcf;border-top:0;padding:0;background:#fff;display:block;}.spec-table-wrapper{width:100%;max-width:1100px;margin:0 auto;overflow-x:auto;}.spec-table{width:100%;border-collapse:collapse;font-family:Verdana,Arial,sans-serif;font-size:12px;color:#111;}.spec-table th,.spec-table td{border:1px solid #d3d3d3;padding:6px 8px;text-align:center;vertical-align:middle;}.spec-table thead th{background:#444;color:#fff;text-transform:uppercase;font-weight:700;}.spec-table thead tr:nth-child(2) th{background:#e9e9e9;color:#111;}.spec-table tbody tr:nth-child(even){background:#f7f7f7;}.spec-table a{color:#0066cc;text-decoration:none;font-weight:700;}.spec-table a:hover{color:#004f99;text-decoration:underline;}@media(max-width:640px){ .spec-table thead{display:none;} .spec-table tbody td{display:flex;justify-content:space-between;align-items:center;border-bottom:1px solid #e2e2e2;padding:8px;} .spec-table td::before{content:attr(data-label);font-weight:700;text-transform:uppercase;flex:0 0 45%;text-align:left;color:#444;}} AVAILABLE VARIATIONS AND SPECIFICATIONS LESS HOSESKUSTANDARD CAPOPTIONAL CAP.Reducer requiredINLET SWIVEL & OUTLET RISERPSIHP SKUHP PSIAPRX.
