It pairs the symmetric LED Core with Hammer's Pearl Urethane coverstock, delivering a smooth, predictable, low-flare motion for dry to medium oil and short patterns. It is the ball you reach for when you need control instead of hook.\n\nThe Purple Pearl Urethane reads the lane gently and predictably. The pearl urethane cover generates less friction and stores less energy than reactive resin, so the ball holds a controlled line where a strong reactive ball would over-hook. It is a dependable choice for short patterns, broken-down lanes, and precise control shots.\n\nUnderstanding the Hammer LED Core and Hammer Pearl Urethane\n\nHammer built the Purple Pearl Urethane for smooth, controllable motion on dry to medium oil. Specifically, the symmetric LED Core posts a 2.650 RG and a low .015 differential, numbers that produce minimal flare and a smooth, on-line motion, while the Pearl Urethane cover at a 2000-grit finish reads the lane gently rather than snapping. As a result, it delivers a controlled, repeatable shape on short and worn conditions. The per-weight specifications are listed below.\n\nA High-RG, Low-Differential Symmetric Core for Minimal Flare\n\nAt the heart of the Purple Pearl Urethane is the symmetric LED Core. At 15 lb it measures a high 2.650 RG and a low .015 differential, numbers that produce minimal track flare and a smooth, controlled motion. The high RG and low differential keep the reaction even and predictable, exactly what a control ball needs.\n\nThat low-flare, on-line behavior is what gives the Purple Pearl Urethane its controlled feel. As a symmetric core, it reads the lane the same way shot after shot, so the ball holds its line through dry and short patterns rather than over-reacting at the breakpoint.\n\nA Pearl Urethane Cover for Predictable Control With a Touch of Length\n\nThe Purple Pearl Urethane wraps that core in Hammer's Pearl Urethane coverstock at a 2000-grit finish. Urethane generates less friction than reactive resin, so the ball reads the lane gently and holds a controlled line instead of snapping at the breakpoint. The pearl additive gives it a touch more length and a slightly cleaner read than a solid urethane.\n\nThat smooth, even reaction is exactly what makes the Purple Pearl Urethane a control weapon. On short patterns and broken-down lanes, it gets a predictable read where a strong reactive ball would jump. Take the surface down for a touch more grip, or smooth it up for a bit more length, with surface changes done at your pro shop.\n\nPurple Pearl Urethane Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Control Players: A smooth, on-line urethane reaction for dry, short, and broken-down lanes\n\n✓Short-Pattern Bowlers: Minimal flare and a predictable read for short patterns where a reactive ball over-reacts\n\n✓Urethane Users: A classic pearl urethane that holds its line on demanding conditions but stays tunable\n\n✓Arsenal Builders: A specialty control piece for the driest and shortest conditions, when angle is the enemy\n\nGood to Know Before You Buy\n\n·Control over raw hook: The lower differential means moderate total hook. For maximum board coverage on heavy oil, step up to stronger equipment.\n\n·Ships sanded for traction: The 2000 Grit finish is built to grip in oil. Polish it for more length when the volume drops.\n\n·Colors vary: Actual colors vary somewhat from the photos shown; no two balls come out of the mold exactly alike.\n\n·Tiny pit holes are normal: A few tiny pit holes in the coverstock are a normal part of the manufacturing process.\n\n·Sold undrilled: Ships without finger holes, so it can be fitted to your hand and span.\n\nBowlersMart Tips: Where the Purple Pearl Urethane Fits in Your Hammer Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Hammer lineup, the Purple Pearl Urethane is a specialty control piece for dry, short, and broken-down lanes. Where your reactive balls hook sharply, the pearl urethane reads smoothly and holds its line. For an even harder, more controllable urethane, step to the 78D versions; for control with more flare, look at the NU 2.0.\n\nSurface Adjustments\n\nThe 2000-grit finish gives the Purple Pearl Urethane its controlled, urethane read. Take it lower for a touch more grip on the driest lanes, or smooth it up for a bit more length. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nWipe the urethane cover with an approved ball cleaner after every session. Keeping the cover fresh preserves the smooth, predictable read that makes the Purple Pearl Urethane such a dependable control piece.\n\nEarn points on every Hammer purchase through the Striking Rewards loyalty program.
