Product Details

The Parker Hannifin 481292 is a Grade 8 hex head cap bolt measuring 5/16-18 x 1-3/4 inches, engineered as an OEM replacement fastener for Parker's replaceable-core refrigerant filter-drier assemblies. Also referenced by Parker's internal part number 4141-1, this bolt ensures a secure, leak-free closure on filter-drier housings used in refrigeration and air conditioning systems.

Key Features:

  • Grade 8 strength rating — high-tensile alloy steel construction with a minimum proof load of 85,000 PSI and minimum tensile strength of 150,000 PSI
  • 5/16-18 UNC thread — standard unified coarse thread for reliable engagement and torque retention
  • 1-3/4 inch grip length — sized precisely for Parker filter-drier housing flange applications
  • Hex head drive — compatible with standard 1/2-inch wrench or socket for straightforward installation and removal
  • OEM Parker replacement part — direct-fit component for Parker Hannifin replaceable-core filter-drier assemblies
  • Yellow zinc or phosphate finish — Grade 8 bolts typically feature a hardened, corrosion-resistant coating suitable for HVAC/R environments

Using the correct OEM fastener is critical in refrigerant filter-drier applications, where proper torque and a secure seal prevent refrigerant leaks and maintain system integrity. The Parker 481292 bolt replaces worn or damaged hardware to restore your filter-drier assembly to factory specification.

Fantastic, in stock, best price, fast shipping with good communications

Great experience. Competitive price.

Quick delivery. Good price.

I'm waiting on my refund. I was not happy that I couldn't talk to a real person regarding my return and my repurchase of the correct prop that I needed. So , if I get my total refund without a huge restocking fee(since the prop is new in original packaging and I bought another prop that is the correct size) then I will be extremely satisfied.

Ordered a tire and received a tire. Took a couple days after shipping tag was created for it to actually ship, but it was a holiday week. Came pretty quick after the FedEx tracking was updated.

Good service and quick shipping

Good experience

Had the tires I wanted at a fair price and delivered quickly! Thank you!

Everything went well. We’ll see how shipping goes.
