Polished Rods

5 grades
Piston steel polished rods

Piston Steel

1045 carbon steel

Designed for light to heavy loads where well fluids are non-corrosive. The best choice for heavy pumping applications where corrosion is not a problem.

Min. 100,000 PSI
4140 alloy polished rods

4140 Alloy

Chromium-molybdenum

For light to heavy loads at any depth in mild to medium corrosive well fluids that are effectively inhibited against corrosion. Alloyed to harden and resist corrosion and abrasion.

Min. 125,000 PSI
PRL hard faced polished rods

PRL-Hard Faced

1045 with hard faced O.D.

Recommended for abrasive and corrosive conditions under moderate to heavy loads. The best corrosion and abrasion resistance of any polished rod on the market today.

431 stainless polished rods

431 Stainless

High strength stainless

Outperforms 1045 or 4140 in corrosive environments, including salt water. Excellent tensile and torque strength makes it ideally suited for PC pumps.

Min. 115,000 PSI
N50 polished rods

N50

NACE · unannealed

Designed to solve the most serious corrosion problems. Excellent corrosion resistance and mechanical properties superior to anything on the market.

Min. 135,000 PSI

Sinker Bars

API Grade 1 and Grade 2
Sinker bars racked in the shop

PRL Manufacturing's sinker bars, made from hot rolled carbon manganese steel bar stock, deliver concentrated weight above the pump to help keep the rod string straight and in tension, which reduces buckling of the sucker rods or the pump plunger.

Sinker bars are surface turned and have API double sucker rod pins, shoulders, and wrench flats on both ends. One end has a reduced section for elevator seating and lifting.

Polished Rod Liners

2 types
PRL hard faced polished rod liners

PRL-Hard Faced

Epoxy resin lined

A unique application of metals produces a liner with the hardness to resist abrasion, coated inside with epoxy resin to protect against corrosion. Recommended when abrasion or corrosion is a problem.

Bronze polished rod liners

Bronze

Special bronze alloy

More resistant to corrosion and harder than regular commercial brass. Highly recommended when corrosion, alignment, or electrolysis is a problem.
