Ridgid RP 251 Press Tool Battery Kit with RLS Jaws (1/4 Inch – 1-3/8 Inch)

Description

Crush copper fitting joints without open flames using the Ridgid RP 251 RLS Press Kit for tight commercial refrigeration runs. The 18V brushless motor drives an inline hydraulic ram yielding 5,400 lbs crimp output across 1/4in to 1-3/8in lines. This configuration trades multi-material versatility for HVAC specialization, requiring separate non-RLS jaws for copper water tubing.

A glass-reinforced polymer shell houses hardened forged steel drive gears with an aluminum gearbox plate. The 18V brushless motor pulls 14A during peak crimp pressure cycles while driving an electro-hydraulic piston. This compact tool chassis weighs 5.6 lbs bare and stretches 15.6in long by 4.3in wide. The reinforced nose casting accepts standard compact series jaws, retaining structural rigidity under repeated mechanical stress inside crowded mechanical chases.

Key Features of Ridgid RP 251

Mechanical contractors buy Ridgid RP 251 packages to eliminate hot work permits on high-rise refrigerant retrofits. Competitive trade pricing reflects specialized equipment that completes leak-free commercial refrigeration joints faster than open oxyacetylene torches.

• Generates 5,400 lbs hydraulic ram thrust to seal high-pressure HVAC connections.
• Full 360-degree head swivel accesses copper tubing tucked between tight ceiling joists.
• Inline barrel profile improves balance inside dense commercial mechanical service shafts.
• Integrated LED work light illuminates dark service corners behind commercial walk-in coolers.
• Microprocessor control verifies full cycle completion before retracting the internal ram roller.
• Hardened steel RLS jaws match precise refrigeration fitting contours up to 1-3/8in.
• Low battery sensor stops incomplete presses during critical line installations.

Hydraulic Ram Bench Runout Tests

Bench testing records a 5-second cycle duration under a 5,400 lbs ram force threshold. Spindle drive runout at the jaw pin pivot measures under 0.0004in TIR across continuous operational tests. Housing temperature stabilizes at 134°F after 50 consecutive crimps on 1-1/8in copper tube couplings. Current draw spikes to 16A at peak clamp force then drops to zero once the internal pressure relief valve pops. Noise levels peak at 76 dB at operator ear level during final ring collapse.

Field Handling Inspection Standards

Trigger pull requires 4 lbs finger pressure with crisp detent feedback through insulated work gloves. The balanced inline chassis rests comfortably in one hand during overhead pipe work. Do not purchase this tool for scheduled pressing of 2in commercial black iron gas lines or schedule 40 carbon steel pipe networks.

• Coat jaw retention pins with NLGI 2 lithium grease every 50 operating hours.
• Wipe internal drive ram rollers with dry microfiber shop towels every 100 crimp cycles.
• Inspect steel jaw contact faces for metal burrs or gouges before each work shift.

Warranty Protection Package Contents

Ridgid provides a Full Lifetime warranty against material defects or assembly flaws. The kit package contains the inline tool body, two 18V 2.5Ah lithium batteries, one fast charger, four RLS jaws spanning 1/4in to 1-3/8in sizes, and one molded field transport case.
