Lippert Components double lip grease seal for RV trailer axles 1.72" ID — 10-pack, double-lip protection

This Lippert double lip grease seal is a direct-replacement axle seal with a 1.72" inner diameter, sold as a 10-pack to protect trailer hubs rated 1,250–8,000 lbs.

When a trailer hub begins to leak grease or let dirt into the bearings, the result is increased wear and unexpected downtime. Lippert Components offers this engineered replacement seal to restore the barrier between axle grease and the environment. It matches common OEM dimensions so installation follows the same steps as the original part, helping you get back on the road quickly.

How does this seal stop grease loss and contamination?

The double lip design creates two protective edges that retain lubricant while blocking water, mud and debris from entering the hub. One lip retains internal grease under normal operating pressure while the secondary lip provides a backup shield during shocks or splash conditions. Together they extend bearing life by keeping contaminants out and lubricant in.

• Double lip geometry for primary and secondary sealing
• Resilient elastomer material resists abrasion and common road chemicals
• 1.72" inner diameter sized to fit specified axle hubs precisely
• Reduces likelihood of premature bearing replacement

Will this fit my trailer axle and hub brand?

Yes — the part is designed as an exact-match replacement for many trailer hubs and fits axles rated from 1,250 up to 8,000 pounds. It comes in a common 1.72" inner diameter for hubs that call for that size, and Lippert engineered compatibility with leading hub brands to simplify maintenance. Always verify your original seal dimensions or hub part number before ordering to confirm the 1.72" ID is correct.

• Compatible with many Lippert, Dexter and Al-Ko style hubs
• Suitable for axles rated 1,250–8,000 lb when hub requires 1.72" ID
• Available in multi-size families if a different ID is needed
• Sold in packs so you can replace multiple axles or keep spares

How easy is it to install and what tools will I need?

Installation mirrors the original factory seal procedure: remove the old seal, clean the bore, lubricate the new seal, and press it evenly into place. Because this is a direct replacement, the seal’s outer diameter and lip profile match OEM geometry, which reduces fitment guesswork. A seal driver or properly sized socket and a mallet are typically all that’s required.

• Clean hub bore and inspect bearings before install
• Lightly coat lip with grease to ease insertion
• Press evenly using a seal driver or socket and mallet
• Check for proper seating and spin freely without binding

Why buy the 10-pack option instead of a single or two-pack?

The 10-pack is cost-effective for fleet maintenance, multiple-axle trailers, or to keep spares for seasonal checks. Buying in bulk lowers per-unit cost and ensures you have matched seals on hand for routine service intervals or unexpected repairs while traveling. It’s a practical choice for repair shops, RV owners with multiple trailers, and anyone planning preventive maintenance.

• Bulk pricing reduces cost per seal
• Good for multi-axle trailers or multiple vehicles
• Ensures spare parts availability during trips
• Standardized replacement simplifies future servicing

Who is this for: This 1.72" inner-diameter Lippert replacement double lip grease seal is ideal for RV and trailer owners, repair shops, and fleet managers who want a reliable OEM-style seal for axles rated 1,250–8,000 lb. Choose the 10-pack if you maintain several trailers, keep spares for seasonal service, or need a cost-effective solution for recurring maintenance.
