Piston Seals - Nitrile lipseals are pressure energized and wear compensating. Their excellent lubrication retention characteristics lower seal friction and ensure long life.

Piston - Solid aluminum alloy, light-weight for low inertia, yet strong.

Head/Cap - Precision machined from solid corrosion-resistant 304 stainless steel bar.

Rod Wiper - Urethane lipseals aggressively wipe foreign material from piston rod and enhance rod seal life.

Rod Seals - Rounded urethane lipseals are pressure energized and wear compensating.

Piston Rod - 303 stainless steel, 40,000 PSI minimum yield, hard chrome plated, ground and polished.

Adjustable Captive Cushion Needle - Allows for safe and precise adjustment under pressure.

Wear Strip - PTFE and graphite composition for minimum friction, maximum wear and side load resistance. (Magnetic band under wear strip optional.)

Tube - Corrosion-resistant 304 stainless steel.

Tie Rods - High-strength 303 stainless steel maintains compression on tube end seals.

Retainer - Stainless steel snap ring securely retains bushing in head.

Rod Bearings - Machined from 304 stainless steel, with a PTFE composite wear band insert that eliminates metal-to-metal contact.

Acorn Nut - Tie rod threads are covered by stainless steel acorn nuts which eliminate another bacteria hiding place.
